Ultra-low-voltage SOI CMOS Inverting Driver Circuit Using Effective Charge Pump Based on Bootstrap Technique

A novel SOI CMOS inverting driver circuit is reported using a concise charge pump based on bootstrap technique (CPBT) for ultra-low-voltage (ULV) VLSI applications. The ULV driver with CPBT composed of a bootstrap capacitor, a pre-charge device and a driver device, provides a four times speed improvement as compared to a counterpart circuit using the direct bootstrap technique at an output load of 100 fF operating at 0.5 V.
