摘要：

A new resistorless voltage-to-current converter utilizing only MOS transistors to achieve voltage-to-current conversion with less than +/-0.5% nonlinearity is described, The circuit uses RIGS transistors in linear and saturation regions to produce an output current linearly related to the input voltage. The output current is proportional to the carrier mobility tracking the process variations. This circuit is suitable for submicron technologies where the availability of a linear resistor with moderate sheet resistance is not guaranteed, The circuit is fabricated using 0.6-mum n-well CMOS technology, consumes less than 200 muA, and occupies 200 mm(2) of area.
