Implementation of CMOS AD/DA Converter Using Pseudo Floating Gate

In this paper, we present Pseudo Floating Gate (PFG) binary and analog inverter with feedback control. The PFG inverter can be used to implement digital multiple valued and analog circuits. Here we construct powerful multiple valued reversible logic structure. The reversible block is implemented by PFG and performs A to D functions and D to A function as its reverse application. The circuit has been implemented in 0.35um CMOS process.
