Abstract:
1. A current-mode folding amplifier circuit, comprising: at least one first current mirroring circuit having a plurality of first current mirrors, each of the first current mirrors having a plurality of metal-oxide-semiconductor field-effect transistors (MOSFETs) configured for current biasing by a corresponding current source biasing current, the at least one first current circuit mirroring circuit being operable to generate a first output current responsive to a current source input current; and at least one second current mirroring circuit having a plurality of second current mirrors, each of the second current mirrors having a plurality of MOSFETs configured for current biasing by a corresponding current source biasing current, the current mirrors including at least one inverting current mirror, the at least one second current mirroring circuit being operable to generate a second output current responsive to the current source input current; wherein the at least one first current mirroring circuit and the at least one second current mirroring circuit are configured to produce a total output current, I wherein the total output current, I
