Abstract:
A circuit is provided that includes a Cartesian feedback loop (400). The Cartesian feedback loop (400) includes one or more operational amplifiers (250a-c). At least one of the operational amplifiers (250a) includes two or more cascaded amplifier stages (420a, 420b) and one or more bypass amplifier stages (422). The bypass amplifier stages (422) are connected in parallel with the cascaded amplifier stages (420a, 420b).
