摘要：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 voltagecontrolled oscillator (VCO). The DCO is implemented using 0.18 μm CEDEC MentorGraphic CMOS process at 2.0 V supply voltage. The simulation results show that theproposed DCO consumed only 9.5764 mW of power besides the output voltage is1.8121 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 theproposed circuits.
