Abstract :
A highly linear voltage-to-current (V/I) converter is presented. A variant of the FVF denoted "flipped folded voltage follower" (FFVF) and a useful application in a voltage-to-current (V/I) converter are presented. A modification using floating gates to provide gain programmability is discussed. Simulation and experimental results of fabricated test chip show the high linearity of the scheme
