(57) [Abstract] [Object] The present invention relates to a ring oscillator and a digital signal inverter used for delay. An electronically controlled variable propagation delay digital signal inverter (eg, 10,710) includes an output terminal pair, an input terminal pair, and an electronically controlled negative resistance (ECNR) (eg, 3). 0) digital signal inverter (eg, 2) 0, 210) is included. The ECNR is coupled to the output terminal pair of the inverter. |
