Wide-Input Range Linear Voltage-to-Current Converter Using Equivalent MOSFETs without Cutoff Region

摘要

A building block for widening an input range under low power-supply voltages is proposed and the block is used in a popular linearization technique for voltage-to-current converters. The block employs two MOSFETs each of which ac- tively works when and only when the other is in cutoff region. Accurate level shift circuits for the control of the MOSFETs en- Able such exclusive operation. Simulation results show that the Complementary MOSFETs perform as an equivalent MOSFET Without any cutoff region. It is also confirmed that the novel Linear voltage-to-current converter is effective for not only a wide Input range but also low-power consumption.
