Non-overlap clock generator is an important building block in many power conversion circuits, such as switch-capacitor DC-DC converters (SC-DCC). Switching circuits use non-overlapping clock signal to prevent shoot-through current during phase transition, which causes power dissipation and degrades efficiency.
We present two methods to generate non-overlapping clock signal in CMOS. The circuit is designed for a recently-proposed SC-DCC for wireless biomedical devices, which uses a three-phase signal for optimum operation.
