N2 - This paper describes a 9-bit digitally controlled oscillator (DCO) that enables the direct proportional loop control by an all-digital negative feedback loop circuit while satisfying a wide frequency range of 3.94 - 8 GHz. The supply voltage of the 4 stage delay cell is adjusted with two digitally controlled resistors (DCR), and the instantaneous frequency change for proportional path application is shown through simulation. The basic operation of DCO has verified with post layout simulation. This circuit is designed with 65nm CMOS technology. The power consumption is 25.1mW with a supply voltage of 1.2V at 8 GHz clock frequency. According to the simulation, the peak-to-peak jitter of the clock is 1.68ps and a phase noise is -82.8dBc/Hz at 1MHz offset frequency.
