Abstract
A differential voltage clamped current mode delay cell is proposed and a three-stage differential ring oscillator is implemented. Owing to the nature of this current mode, with voltage clamping and robustness against noise, experimental results show that the supply sensitivity is very low at ~0.1-0.2%/V in the 500-800 MHz range, with its tuning range over 1 decade up to 1.38 GHz
