Abstract

A wide range digital leakage current mismatch compensator for a short-channel charge pump (CP) circuit is presented. Equipped with leakage current generators and leakage current mirrors, the proposed leakage current mismatch compensator can reduce the PMOS and NMOS leakage current mismatch to less than 1/10 times of its initial value for wide range of leakage current mismatches. For simulation, a CP circuit with the proposed leakage current mismatch compensator was designed in a 0.13µm 1P8M CMOS process.
