CMOS ring oscillator with combined delay stages
چکیده انگلیسی

Full transistor voltage control oscillators by delay stages are studied in this paper. First we describe the general conditions of oscillators and after introducing some common inverters, calculating their delay times, we analyze the dependence of delay time to variation of power supply voltage. The analyzing results show that the delay of basic type inverter varies in the opposite direction as that of current starved inverter, therefore to achieve better frequency stability versus voltage power supply changing, some combined structures of inverters are presented. The results of simulation by 0.18 CMOS technology library of HSPICE approve the analysis results.
