A Low-Jitter Cell-Based Digitally Controlled Oscillator With Differential Multiphase Outputs

A low-jitter digitally controlled oscillator (DCO) with multiphase differential outputs and good linearity is presented. The DCO is composed of four differential delay cells and can achieve linear tuning over a wide frequency range. The proposed fully differential delay cell comprises logic cells in...
