Abstract :
A new CMOS OTA which consists of a linearized source-coupled pair cascaded by a conventional CMOS OTA biased in sub-threshold region is presented. SPICE simulation results show that for ±5 V supply voltage, and over ±3 V input range, the maximum non-linear error is ±0.3% and the transconductance varies Iabc linearly over a wide Iabc range
