The VTC considered in this work is based on a starved-inverter topology. Linearity, delay, and jitter of the VTC are analyzed to facilitate a physical understanding of the circuit performance. The design is experimentally verified in a 65-nm CMOS technology. Measurement results show that the VTC, operating with a 5-GHz clock, has an output delay range of $$\pm 25\,{\text{ ps }}$$ ± 25 ps , 4.4 effective number of bits (ENOB), and output jitter of $$0.5\,\text{ ps }$$ 0.5 ps RMS while consuming 4mW of power. The input effective resolution bandwidth (ERBW) of the VTC is measured to be 4.1GHz, over which the ENOB remains above 3.5 bits. The same VTC, operating with a 7.5-GHz clock, consumes 9.7mW of power from a 1.2-V supply, has ENOB of >3.8 bits, ERBW of >7GHz, output jitter of $$0.4\,\text{ ps }$$ 0.4 ps RMS, and output delay range of $$\pm 25\,\text{ ps }$$ ± 25 ps . The VTC achieves the widest input bandwidth of any VTC reported to date.
