2-MOSFET transresistor with extremely low distortion for output reaching supply voltages

Square-difference is a new and very attractive linearisation technique. It has been successfully used to implement large-signal MOS transconductors. A transresistor realised with only two MOS devices using the same technique is presented. A linearity error of less than ±0–5% for the output swing from supply voltage Vss to VDD is achieved.
