A circuit technique based on two CMOS crosscoupled pairs for realising a linear CMOS transconductor of class AB is presented. Design tradeoffs are discussed and a circuit example is presented. SPICE simulation results show that, for a power supply of ±5 V, the linearity error is controlled to ±1% over a ±3 V input range.
