This paper presents a wide linear range transconductor based on the differential pair with emitter/source degeneration. The proposed circuit can be implemented in both bipolar and CMOS technology. The transconductor exhibits high linearity that is achieved by forcing a constant current through the main transistors in the differential pair and collecting the output current by means of two additional transistors and two current mirrors. Simulation results are presented for a CMOS implementation operating at a 1.8 V supply voltage.
