Abstract: The addition of current feedback loops to the cross-coupled CMOS transconductor cell to reduce the quiescent currents while maintaining comparable linearity is described. The circuits were simulated in SPICE using BSIM models and a power supply of ±5 V. Denoting ε as linearity error, Vid as differential input signal and fc as cut-off frequency, |ε| < 1% for |Vid| < 1.3 V, fc = 130 MHz and static power consumption of 5.2 mW are obtained if the output is single-ended. If differential output is employed, |ε| < 0.6% for |Vid| < ±2.4 V, fc = 80 MHz and static power consumption of 6.1 mW are obtained. In both cases, the THD for a Vid = 1 Vpp at 1 kHz is 1.3%.
