A low-power, capacitively-divided, ring oscillator with digitally adjustable voltage swing


A capacitively-divided, injection-locked, ring oscillator is proposed that decreases dynamic power consumption by reducing voltage swing. A feedforward capacitor is placed in series with the load capacitance, effectively AC coupling each inverter stage to the next stage. Simulations are performed using digital programmability of the capacitor weights of… (More)
