Abstract
A non-linear bulk capacitance bootstrapped current switch includes a current switch circuit including a source node and a first bulk connection having a first bulk capacitance associated with it; a current defining circuit connected to the source node and having a second bulk connection having a second bulk capacitance associated with it; and a tracking circuit for driving the voltage on at least one of the first and second bulk connections in response to the voltage on the source node to reduce the associated non-linear bulk capacitance.
