Abstract :
In this paper, the compact model of power efficiency for four-phase negative charge pumps is derived. By including parasitic effects in the pump, discrepancies between the model and the post-layout simulated results are within 6%. The proposed four-phase negative charge pump was fabricated by a 0.25 mum flash memory technology. Due to the special body potential controlled structure to minimize body effects and noise due to PN junction conduction, it can pump to -10.3 V at 1.2 V supply voltage with 10 stages.
