Abstract
A variable gain differential transimpedance amplifier (TIA) optimized for MEMS-based oscillator applications is presented. The TIA achieves a variable gain of 17 kOmega to 290 kOmega, i.e. a gain range of 25 dB. The 3-dB bandwidths corresponding to these gains are 256 MHz and 103 MHz, respectively. The suitability of the TIA for the targeted application is demonstrated by combining it with a MEMS resonator to create an oscillator at the frequency of 8.29 MHz, with a phase noise of -89 dBc/Hz at a 1 kHz offset frequency.
