Abstract
A low power local oscillator with a free running frequency of 950 MHz and a DC power consumption of less than 1 mW has been designed. It can be locked with a single or differential -30 dBm lock signal on the second harmonic and uses no dedicated lock transmission gate. The fully differential circuit employs a two stage ring oscillator and provides the possibility of using differential I- and Q-outputs.
