摘要：
A new CMOS transconductor with wide transconductance tuning range and very low distortion is presented. The input stage features a highly linear conversion of the input voltage into current form. Electronically programmable current mirrors able to operate in weak or moderate inversion provide a continuous transconductance tuning range of two decades without affecting the large input signal range available. Measurement results of a prototype fabricated in a 0.5-mum CMOS technology show a THD of -66.5 dB for a 100-kHz differential input of 2 V-pp.
