| Summary: | This paper presents the design and simulation of
microelectromechanical system (MEMS) based oscillator based
on CMOS MEMS surface acoustic wave (SAW) resonator and
regulated cascode configuration (RGC) transimpedance
amplifier (TIA). The proposed TIA is designed in a standard 0.18
μm Silterra CMOS prosess via Cadence Virtuoso software. Gm/ID
technique is used to achieve higher gain and low power TIA. The
simulation result shows that the voltage gain of the design circuit
is 35.5dB and 2.08 GHz -3dB bandwidth. The circuit consume
1.6mW power at 1.8 V supply voltage. When integrate with
1.4GHz resonator, the phase noise of this oscillator is -105.27
dBc/Hz at 1kHz and -116.03 dBc/Hz 10kHz. |
