공급전압의 변화에 영향을 받지 않는 4㎒ RC 발진기 설계

In this paper, an RC oscillator which is stable against not only supply voltage variations but also temperature and process fluctuations is proposed. The proposed oscillator was verified by 0.35㎛ CMOS process parameters and maintains stability within 1% against supply voltage at a range of 2~3.6V. The proposed oscillator consumes 2㎽ at a supply voltage of 3V.
