  • Ring oscillator using CMOS technology
    Patent number: 6127898
    Abstract: A ring oscillator using CMOS technology having three logic gates, including a threshold amplifier, where the transistors that set the voltage rise threshold and the voltage drop threshold in the amplifier are controlled by a bias control circuit so that the ratio of voltage rise threshold to the voltage supply diminishes and the ratio of the voltage drop threshold to the voltage supply increases, when the supply voltage falls.
