A low power high efficient radio frequency clock generator for bio-implants

Abstract

Now a days in VLSI, System on Chip (SoC) design is replacing the systems on board due to its high performance, less area and low power. Though Complementary Metal Oxide Semiconductor (CMOS) devices are playing a key role in the realization of low power million transistor circuits are not useful in sub-threshold region due to their charge leakage. The major abnormalities of these devices are jitter, skew and high power consumption which is amplified in Radio Frequency (RF) range. This paper deals with the realization of a Real Time RF Clock Generator circuit implemented with Carbon Nano Tube Field Effect Transistor (CNTFET) and Fin Field Effect Transistor (FINFET) devices is considered for clocking digital circuits in RF range. RF clock uses differential amplifier with buffer signal, provides less offset frequency, fast data transmission, susceptible at low voltage level and reduce jitter. The power dissipation, area and performance of these circuits are compared with the CMOS circuits with power supply of 1.8v and frequency of 2 MHz. It is observed that —% power, —% of area and —% of delay are reduced.
