In this paper, two CMOS analog signal processing circuits which could find wide use in low-voltage VLSI applications are presented. The two circuits include a voltage-to-current converter (V-I converter) and a multiplier. Both of the circuits can operate from rail to rail with a power supply of 3V. They were fabricated in a 2μm N-well double-poly CMOS process by MOSIS. In either of the circuits, an N-type circuit cell is connected in parallel with its P-type counterpart to achieve common-mode rail-to-rail operation. For the V-I converter, a nominal value of a 200μS transconductance with a tuning range of 0.5 to 2 is obtained when the input signal swing is 1 VPP. For the analog multiplier, it is realized by a parallel connection of the two V-I converters. Both of the input signal swings of the multiplier are measured as 1VPP and 1.6VPP, respectively.
