Analog chip is the bridge between reality and virtual, and is an important part of semiconductor industry. Due to its slow product iteration, long life cycle, the need for long-term accumulation of experience, so the industry has always been known as "one year of digital, ten years of simulation".

It is understood that Ju Xun Semiconductor was founded in 2016, is a global chip design high-tech enterprise, focusing on high-performance, high-quality simulation and mixed signal products research and development design and sales. At present, the company has operational amplifiers, comparators, analog switches, analog-to-digital converters and other product lines, widely used in communication networks, consumer electronics, industrial control, automotive electronics, the Internet of things and other fields, its cumulative shipments have exceeded 500 million. "The company's products are mainly signal chain analog chip operational amplifiers, and gradually into converter and interface product chips and power management chips. After years of development, we now have more than 100 product models available for sale, and the performance of many products has reached the international leading level. With excellent comprehensive performance, the company's products have entered the supply chain system of many well-known customers such as Xiaomi, Midea, Galanz, Yingqu technology, Xinwangda, Vision source shares, Scud, Kangtai Medical." Zhang Zhicai introduced a way to reporters.
As the company's main product, operational amplifier is an electronic integrated circuit with multistage amplifier. In the actual circuit, the feedback network is usually combined to form a certain functional module. The input stage is a differential amplifier circuit with high input resistance and zero drift suppression capability. The intermediate stage is mainly for voltage amplification, with high voltage amplification, generally composed of common emitter amplifier circuit; The output pole is connected with the load, which has the characteristics of strong load capacity and low output resistance.
Currently, there are many types of op-amp, including high-speed operational amplifier, low noise operational amplifier, low voltage low power operational amplifier, high-pressure general operational amplifier, low voltage level, operational amplifier, and zero drift operational amplifiers, operational amplifiers, low power consumption, such as high precision general operational amplifier is widely applied in the electronics industry in many fields. "Signal amplification is the most common function of analog signal processing and is typically achieved through an operational amplifier connected to a dedicated amplifier circuit. At present, we are the industry's few products more complete operational amplifier manufacturers, has been mass production of op-amp products have low noise op-amp, zero drift op-amp, high-speed op-amp, low-power op-amp, Na 'an class op-amp, etc., in addition to high voltage and high precision op-amp has entered the trial production stage. Zhang Zhicai said, "as the company's main products, operational AMP shipments in more than 100 million each year, the cumulative turnover of customers has exceeded 1000, the main customers are BYD, Xiaomi, Youlide, Gao Biao and so on."
In terms of zero drift operation, POLY XUN SEMICONDUCTOR mainly adopts TSMC advanced CMOS process and new chopper circuit structure design, which can provide very low input offset voltage, and the input offset voltage is close to zero drift with the passage of time and temperature changes. In terms of low-voltage and low-power operational amplifiers, the GS600X series is specially designed for a variety of low-voltage general applications. This series of amplifiers has A 1MHz gain bandwidth product, A minimum operating voltage of 1.8V, A voltage conversion rate of 0.8V/μs, A static current of only 75μA at A 5V supply voltage, and an integrated anti-RF interference function.
With the decrease of circuit supply voltage, the design of low voltage op-amp is becoming a research hotspot. According to Zhang Zhicai, Ju Xun low-voltage and low-power op-amp chips include single-channel GS6001, dual-channel GS6002, four-channel GS6004, etc., which can be used in sensor interfaces, smoke detectors, medical instruments and portable systems. Among them, the lowest operating voltage of GS6001 can be as low as 1.8V. This new rail-to-rail low-voltage transportation has a great competitive advantage compared with its peers in terms of cost, and can be used in iot sensing devices, portable instruments and meters, smart home and other application scenarios.
As well known in the industry, analog chip refers to the chip that processes natural analog signals such as continuous light, sound, electrical/magnetic quantities and temperature, etc. According to the product type, it is mainly composed of power management chip and signal chain chip. Among them, signal chain chip refers to the integrated circuit that has the processing ability of transmitting, transmitting, converting, amplifying and filtering analog signals, accounting for about 47% of analog chips.
Juxun Semiconductor since its establishment, always adhere to the continuous innovation of technology and products, and constantly increase R&D investment to expand product categories and iteration upgrade, in order to meet the various needs of analog chips in various downstream market segments. After believe and 琻 jie electronic qiangqiang cooperation, the company will further improve the competitiveness of the products in the market, in order to realize the scale and the profits increased steadily.
