FGMOS, a MOSFET with an additional electrically isolated gate known as floating-gate, has been used in digital circuit design for quite some time with applications in the design of memories. The charge stored on the floating-gate affects the conductivity of the channel and in turn alters the threshold voltage. This imparts programmability to threshold voltage of a FGMOS to make it suitable for low voltage analog circuit structures. Analog circuit structures and their applications in analog signal processing based on standard FGMOS technology at a nominal supply voltage of 0.75 V has been...
