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