S1 is then changed to position 1. The voltage stored on C1 is inserted between the output and inverting input of the amplifier and the output of the amplifier changes by VIN to maintain the amplifier input at the input offset voltage. The output then changes from (VOS + IbiasR2) to (VIN + IbiasR2) as S1 is changed from position 2 to position 1. Amplifier bias current is supplied through R2 from the output of the amplifier or from C2 when S1 is in position 2 and position 1 respectively. R3 serves to reduce the offset at the amplifier output if the amplifier must have maximum linear range or if it is desired to DC couple the amplifier.

The ways of parallel resonant DC link and three-level control strategy were used in this power amplifier circuit. Output current ripple of power amplifier can be reduced as three-level power amplifier, all of power switches work on and off under the zero voltage switching or zero current switching, loss of switching and current ripple interference effectively reduced.

Operational Tran conductance lifers and Grounded actorhas become one of the most important methods to implement integrated continuous-time filters. Operational Tran conductance Amplifierscan transfer input voltage into current to output,and control or change output current within large range by an external controlling current of amplifier. Most articles consider OTA as a voltage-mode circuit component and give voltage-to-voltage transfer function of all having been implemented filter circuits,i.e. The input signal and output signal of filter circuits are voltages .
