Analog ics usually include various amplifiers, analog switches, interface circuits, wireless and RF ics, data conversion chips, all kinds of power management and driver chips, etc., whose design is mainly through experienced designers to carry out transistor level circuit design and corresponding layout design and simulation.
Analog IC is used to generate, amplify and process a variety of analog signals (refers to the amplitude of continuous change over time signal) circuit, is one of the core technologies of microelectronics technology, voltage or current and other analog quantities for acquisition, amplification, comparison, conversion and modulation.
