Abstract :
Complementary current mirror inverters have large bandwidth, small time delay but small gain whereas complementary inverters have high gain but large time delay. Ring oscillators have been realised using a combination of both types of inverter to achieve stable high frequency oscillation. Voltage controlled oscillators were obtained by tuning the frequency of oscillation with supply voltage.
