| Summary: | This paper presents the design and simulation
results for a multi-frequency oscillator based on complementary
metal oxide semiconductor (CMOS) microelectromechanical
systems (MEMS) surface acoustic wave
(SAW) resonator. Multi-frequency oscillator is simulated
using 0.35 μm CMOS technology. The oscillator operated
at 600 and 1.76 GHz. The multi-frequency oscillator shows
phase noise performance of −67.35 and −92.83 dBc/Hz
at 100 kHz offset frequency for 600 MHz and 1.76 GHz,
respectively, during simulation. The pierce circuit topology
was used to sustain the oscillation from CMOS SAW
resonator. The sustaining circuit was design and fabricated
in 0.35 μm CMOS technology process with 3.3 V supply.
The measured S21 of sustaining circuit topology are 6 and
2 dB at 1.76 GHz and 600 MHz, respectively. The phase
responses for 1.76 GHz and 600 MHz are −50° and –200°
correspondingly. |
