Abstract :
This paper proposes a new current amplifier circuit totally formed in the class AB structure utilizing CMOS inverters and the recently proposed additive analog inverter using floating-gate MOSFETs. Operating in a negative feedback topology, the amplifier can deal with wide signal swings up to ±200 μA, with 1% of the THD and 10 pF of CL. Designs and HSPICE simulation results are demonstrated on 0.5 μm double poly CMOS processes with 1.5 V and 1 V power supplies to indicate high frequency and low power capabilities respectively.
