Abstract

A 76 dB-0 hm 1.7 GHz tunable CMOS TIA in 0.18 μm CMOS for lateral micromechanical oscillators is presented. The 7.2 mW TIA uses a low-power broadband current pre-amplifier for gain boosting (loading > 2 pF). The TIA is interfaced with 724 MHz and 1.006 GHz resonators and achieves phase noise better than -87 dBc/Hz and -94 dBc/Hz at 1 kHz offset, respectively.
