   Abstract:
   A high-speed signal conditioning circuit is presented that can be programmed for correction of nonlinearity in a sensor signal processing system. The function of the circuit is based on piecewise linear principles. Post-fabrication programming to adapt to existing nonidealities is done with floating gate devices fabricated in standard technology. Modeling of the sensor nonideality is not required. The circuit is a voltage-to-current converter with an input range of the full power-supply voltage swing. In a 12-module implementation in 2-μm CMOS technology less than 0.5% error over a rail-to-rail input range and a speed of 10 MHz were achieved. The circuit is useful where a signal from a sensor with nonlinearity and high variation in its parameters has to be conditioned for further processing
