CHARGE PUMP CIRCUIT FOR PROVIDING VOLTAGES TO MULTIPLE SWITCH CIRCUITS

摘要

A charge pump circuit generates a charge pump voltage that powers a bias circuit. The bias circuit generates a reference current and generates switch currents from the reference current. Gate-source voltages are generated from the switch currents and applied to switching components of switch circuits to connect two nodes. The gate-source voltages can be generated in the bias circuit and provided to the switch circuits. The gate-source voltages can also be generated in the switch circuits.
