説明
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 two circuit blocks. One of them consists of a single MOSFET operating in plural regions and the other a pair of MOSFETs in saturation region and cut-off region. Combination of the circuit blocks achieves a linear voltage-current conversion for a rail-to-rail input signal. 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. As an application example, 2nd-order LPF is realized using the proposed OTAs.
