|Abstract:||Simple modifications to the cross-coupled CMOS transconductor cell that reduce the quiescent currents while maintaining comparable linearity are described. SPICE simulation results show that using BSIM models and a ± 5 V power supply, the linearity error is less than 0.6% over a differential input voltage range of ± 1.3 V in the case of single-ended output, and less than 0.3% over a differential input voltage range of ± 2.4 V in the case of differential output. The cut-off frequency and power consumption are 130 MHz and 5.2 mW in the case of single-ended output, and 80 MHz and 6.1 mW in the case of differential output. In both cases, the THD for a differential input voltage of 1Vpp at 1 kHz is 1.3%.|
