- Abstract
A low power 6-bit CMOS ring based digitally controlled oscillator (DCO) design is presented. The design is proposed based on binary-to-thermometer (BT) decoder current mirror digital-to-analog converter (DAC) and ring-based voltage controlled oscillator (VCO). The DCO is implemented using 0.18 µm CEDEC Mentor Graphic CMOS process at 2.0 V supply voltage. The simulation results show that the proposed DCO consumed only 9.5764 mW of power besides the output voltage is 1.8121 V and local oscillator clock frequency is 33 MHz. The phase noise parameter is - 132 dBc/Hz with an offset frequency of 100 kHz has also been reported for the proposed circuits.
