Abstract
A programmable clock booster system including a clock booster circuit including at least one boost capacitor connected between a first node and a second node for sampling an input voltage in a first phase and applying a boosting voltage to said second node during a second phase, and a programmable capacitor circuit connected to said first node for providing a programmable boosted voltage on said first node during said second phase.
Claims39
A programmable clock booster system comprising:
- a clock booster circuit including at least one boost capacitor connected between a first node and a second node for sampling an input voltage in a first phase and applying a boosting voltage to said second node during a second phase;
- and
- a programmable capacitor circuit connected to said first node for providing a programmable boosted voltage on said first node during said second phase.
A programmable clock booster system comprising:
- a clock booster circuit including at least one boost capacitor connected between a first node and a second node for sampling an input voltage in a first phase and applying a boosting voltage at said second node in a second phase;
- a capacitor circuit connected to said first node for providing a variable boosted voltage between said input voltage and the sum of said input voltage and said boosting voltage;
- a series-pass switch connected to said capacitor circuit for preventing said variable boosted voltage to pass to an output node in said first phase and allowing said variable boosted voltage to pass to said output node in said second phase;
- and
- a gate drive circuit connected to a gate of said series-pass switch for adjusting the voltage at said gate to a first predetermined voltage that disables said series-pass switch in said first phase and for adjusting the voltage at said gate to a second predetermined voltage that enables said series-pass switch in said second phase.
