In current-mode signal processing, a companding integrator is attractive from the viewpoint of linearity under a low power supply voltage. In this paper, new instantaneous companding integrators using MOSFET's are proposed. The companding integrator utilizes a nature of MOSFET square law. HSPICE simulation results demonstrate several advantages of the proposed circuits.
