ABSTRACT:
A bias generator circuit having a zero-current shutdown state is provided. When on, the bias generator circuit provides substantially constant bias currents (sourcing and/or sinking) and may be selectively turned on and off in response to first and second control signals. When the bias generator is off, it is in a zero-current shutdown state such that substantially no quiescent current is used.
