“…A recent breakthrough brought forward the concept of voltage reference based on charge difference on floating gate (FG) FETs [6], [7] and the same in a beta multiplier circuit [8]. Though this sub 1V reference introduces a new dimension of field programmability, yet their narrow range of programmability or no programmability, and single output voltage, limits its wide applicability.…”

We presents an on-chip tunable wide ranged multiple output CMOS voltage reference based on non-volatile highly precise field programmable floating gate transistors. The reference is outfit for both sub 1V and above 1V applications. The circuit design consists of basic beta multiplier configuration and offers a strategy of making the current sourcing circuit and reference generating circuit as independent units. A simulation model of the circuit was built in T-Spice, 0.35µm CMOS process. Simulation results show high amount of temperature insensitivity for a large range of thermal conditions. The reference voltage variation is about 1.65mV/°C to 1.67mV/°C over wide temperature range of -40 to 140°C; has an impressive static supply dependency of 125µV/V for a reference of 280mV. The circuit can also be operated at very low supply voltage (0.5v).
