Abstract
A bootstrapped switch circuit can include a switch transistor, having a drain configured as an input terminal to receive an input signal, and a voltage-controlled voltage source, configured to provide predetermined constant voltages between a gate and a source of the switch transistor in response to a control signal received at a control terminal. The predetermined constant voltages can include a first predetermined constant voltage to turn on the switch transistor and pass the input signal to the source and a second predetermined constant voltage to turn off the switch transistor. The first and second predetermined constant voltages can be independent of the magnitude of a signal passed to the source of the switch transistor based on the input signal at the drain.
