Abstract

Aiming at the problem that the frequency and phase adjustment of ring oscillator requires changing the number of inverter stages and analog switch’s selection position, a fixed number of stages programmable differential ring oscillator is proposed. By adding an exclusive-OR gate to the input of the traditional differential delay unit, a new differential delay unit is designed. The new differential delay unit can be programmed to perform inverter or fixed delay unit. Through the truth table of the new differential delay unit, when the control logic level is low, the new differential delay unit performs the inverter unit. When the control logic level is high, the new differential delay unit performs the fixed delay unit. Using a fixed number of stage, multiple stages in series, and closed-loop feedback connection, a fixed number of stage programmable differential ring oscillator is designed. By programming the number of high and low logic levels at the control logic, the number of inverter and fixed delay units is set. So the programmable differential ring oscillator can achieve the frequency and phase adjustment. Taking a four stages programmable ring oscillator as an example, how to achieve frequency and phase adjustment of is introduced. In the multisim, the circuit simulation of the programmable differential ring oscillator is performed. The programmable differential ring oscillator achieves frequency which include 1, 2, and 4 divisions and phase adjustment. It is verified that the programmable differential ring oscillator can achieve frequency adjustment and phase adjustment without reconfiguring the circuit.
