A New CMOS Current-Mode Folding Amplifier
In this paper, a new CMOS current-mode folding amplifier is proposed. The circuit is designed using MOSFETs operating in strong inversion. The design produces a nearly ideal saw-tooth input-output characteristic which is a mandatory requirement in folding analog-to-digital converters. The functional...

| Summary: | In this paper, a new CMOS current-mode folding amplifier is proposed. The circuit is designed using MOSFETs operating in strong inversion. The design produces a nearly ideal saw-tooth input-output characteristic which is a mandatory requirement in folding analog-to-digital converters. The functionality of the proposed circuit was confirmed using Tanner simulation tools in 0.35 µm CMOS technology. Simulation results are in excellent agreement with the theory. |
