摘要
This paper proposes an integrator based on the local-feedback voltage amplifier and offset voltage compensation. The local-feedback voltage amplifier has advantages in terms of large dynamic range, smaller chip area, and lower supply voltage operation compared to the conventional operational amplifier. However, there is a drawback that it can have a significant offset voltage due to its circuit structure. The compensation circuit proposed in this paper mitigates it. Simulation results of the proposed circuit show smaller offset voltages with no significant impact to the signal transfer characteristics.
