1. A programmable analog circuit block having programmable power management comprising: an operational amplifier circuit for driving a load; a plurality of paired current sources located within said operational amplifier circuit, wherein a first current source in each pair is coupled in a first parallel configuration to a first node that is coupled to transistors receiving input voltages to said operational amplifier circuit, and a second current source in each pair is coupled in a second parallel configuration to an output of said operational amplifier circuit, wherein a ratio of the amount of current between said current sources of each pair of current sources is proportionally equal; a bias supply signal for generating a given bias voltage; and a plurality of configuration bits for selectively applying said given bias voltage to an associated pair of current sources in order to modulate the performance of said operational amplifier circuit.
