摘要： An amplifier circuit including an input amplifier, an output amplifier and a diode device is provided. The output amplifier is coupled to the input amplifier and outputs an output voltage. The diode device is coupled between an output end and an input end of the output amplifier. When a voltage difference between the output end and the input end of the output amplifier is greater than a barrier voltage of the diode device, the diode device is turned on, and an overshoot of the output voltage is reduced.

摘要： An amplifier circuit with overshoot suppress scheme including an input amplifier, an output amplifier, and a diode is provided. A first and a second input ends of the output amplifier are coupled to a differential output pair of the input amplifier. The diode is coupled between an output end and the first input end of the output amplifier. When the voltage difference between the output and the input ends of the output amplifier is greater then the barrier voltage of the diode, the diode is turned on, so that the output end of the output amplifier is coupled to the input end of the output amplifier. In the transient state, it rapidly smoothes the overshoot signal. In the steady state, the diode is cut off to maintain the normal operation of the operational amplifier.

摘要： A non-isolated power supply. A positive power and a negative power are respectively formed by charging a +VCC1 energy storage filter and a −VCC2 energy storage filter connected in series and discharging the +VCC1 energy storage filter 102 and the −VCC2 energy storage filter. The output positive and negative power may be differently combined by changing the capacities of the +VCC1 energy storage filter and the −VCC2 energy storage filter and may be equal or unequal.
