Research on Stability of a 4-Channel Amplifier in Engineering Applications

With the increasing application of computers, various analog signals (such as fire alarm/cabin door/fuel volume/control valve, etc.) need to be collected and calculated in the field of electromechanical control of aircraft. The conditioning circuit in these signal acquisition circuits is essential, and a large number of high-speed or low-speed amplifiers are used in the conditioning circuit. The stability of the amplifier determines whether the signal acquisition is stable, reliable, and accurate, Therefore, the stability analysis of amplifiers, as well as the gain and noise figure, are necessary factors to consider in the design of amplifier conditioning circuits. Based on these factors, an amplifier that can work stably and reliably in various harsh environments, such as gain, bandwidth, and noise, can be designed, truly reflecting the real-time changes of the input signal in the previous stage.
