Abstract
This paper demonstrates an analog field programmable RC Oscillator using a Floating-Gate Transistor. The programmable oscillator can attain a continuous range of time-periods lying in the programming precision range of Floating Gates. Floating-gate transistors add a programmability feature to the analog circuit making it a wide frequency range square wave generator. The circuit consists of two sub circuits: Current Generator circuit and Wave Generator circuit. The current of current generator circuit is programmable and mirrored to the wave generator to generate the desired square wave. A simulation model of the circuit built in T-Spice, 0.35µm CMOS process. The circuit results in a clock with continuously changing frequency. The circuit can also be operated at a very low supply voltage (1.8V). Theoretically estimated, effective chip area of the circuit is less. The variations with change in temperature can be compensated.
