A new CMOS current controlled ring oscillator is investigated. It is based on a 3 stage ring oscillator. Each stage uses a simple NMOS for switching a current source to charge a capacitor and discharging it thereby generating a ramp output. Its oscillation frequency depends on the current source. Th...
