A reconfigurable dual-mode multiple stage operational amplifier circuit includes a configurable portion that can be selectively configured to operate in either a one-pole mode or a two-pole mode. Different exemplary operational amplifier circuits are provided, some of which employ a compensation portion that can be selectively coupled to the configurable portion. For example, in the one-pole operating mode the compensation portion is decoupled from an output of the configurable portion. Conversely, in the two-pole operating mode the compensation portion is coupled to the output. The compensation portion is configured to stabilize a signal on the output. The configurable portion switches between operational modes in response to at least one control signal. The operational amplifier may include a pulse generating portion that is coupled to operatively control the configurable portion in response to the at least one control signal. Such an implementation negates the need for a compensation portion.
An operational amplifier circuit comprising a configurable portion that can be selectively configured to operate in at least two operational modes including a one-pole mode and a two-pole mode.
