Abstract
In this paper, rail-to-rail OTA utilizing linear V-I conversion circuit whose input stage is composed of single channel MOSFETs, is proposed. The proposed conversion circuit is realized with a pair of MOSFETs. The linear conversion is achieved by changing the regions of the two MOSFETs alternately. Rail-to-rail OTA is proposed using the proposed conversion circuit. HSPICE simulations are performed to verify the validity of the proposed V-I converter and rail-to-rail OTA. Simulation results indicate good performances.
