Abstract
Low power applications entail the use of alternatives for phase-locked-loops in frequency synthesis for transmitter and receiver circuits. Regarding this idea, a ring oscillator based on the injection-locking principle has been designed on Cadence Spectre using the UMC 180 nm process technology. The ring oscillator operates at an ISM band (432 MHz) and dissipates 308 μW with a nominal duty cycle of 50.6% and a phase noise of-98.9 dBc/Hz (at an offset frequency of 100 kHz). The low-power operation capability makes the circuit a suitable candidate for biomedical applications.
