  • Abstract
    A constant-Gm highly linear transconductance (Gm ) cell based on the use of a linear passive resistor and feedback technique is presented. The high-frequency linearity properties of the circuit are investigated using the Volterra analysis method. Simulation results of a linearity-optimized Gm element in 0.35 mum CMOS are presented showing a THD of -75.7 dB at 50 MHz for a 1.8 Vp-p input signal
