CHARGE PUMP CIRCUIT

摘要

A charge pump circuit reduced in spike-like noise (glitch), comprising a first transistor connected at one terminal thereof with a high-potential power supply and operated on/off according to a charge-up signal, a second transistor connected at one terminal thereof with a low-potential power supply and operated on/off according to a charge-down signal, a first current limiting element connected between the other terminal of the above first transistor and a charge pump output, and a second current limiting element connected between the other terminal of the second transistor and a charge pump output.
