ABSTRACT

self-oscillating mixer is introduced in this paper, with fundamental signal generated by the oscillator subcircuit in the process of mixing. The oscillator core consumes 3 mA of the current from a 1.8 V DC supply and leads to an output power of –0.88 dBm per oscillator, and a measured phase noise of –91, –102 and –107 dBc/Hz at 100 KHz, 600 KHz and 1 MHz from the carrier, respectively. The proposed mixer achieved IIP3 of 0 dBm in the process of mixing, with conversation gain of 1.93 dB. Designing and simulation the circuit was done in 0.18 μm CMOS technology by ADS2010.
