A Novel Voltage-Controlled Oscillator Suitable for Silicon-Based Microdisplay Driver Clock

In order to provide silicon microdisplay drivers a wide tuning range clock and solve the problem that the tuning range of VCO is not wide enough, a wide tuning range multi-band feedforward differential delay cell based on CMOS inverter is proposed in this paper. The cell achieves the wide-tuned multi-band effect by adjusting the control voltage (VCTRL) and the control voltage sequence bits. In the HLMC 55LP process, the differential VCO can be adjusted from 3.92GHz to 8.63GHz to achieve a wide tuning range of multi-band output with a FOM of −157.02dBc/Hz.
