Abstract
There is provided an oscillator, having an input terminal (In) and an output terminal (Out), comprising a first signal delay circuit (104a-d), having a first voltage response characteristic, configured to provide a predetermined first propagation delay; a second signal delay circuit (104e, 108, 110), having a second voltage response characteristic that is inversely correlated to said first voltage response characteristic, operatively coupled with said first signal delay circuit and configured to provide a predetermined second propagation delay, and wherein said predetermined first propagation delay and said predetermined second propagation delay are temporally matched, so as to generate an oscillating output signal (Out) of a predetermined frequency.
