“…All TIAs compared have their own strengths and weakness. For example, the work described in [3] achieves a very low power dissipation of 7.2 mW, so if the TIA is conceived for low-power applications and gain and bandwidth are not a concern, this is an excellent solution. Analogously, the work described in [4] achieves a record BW of 22 GHz.…”

This paper presents the design of a framework for the optimization of a low-power, low-noise, broadband transimpedance amplifier to be used in a fiber optic transceiver. The design is implemented using a 180 nm six-metal-layer digital CMOS process with a 1.8V supply. The performances achieved are a gain of 78.34 dB , a bandwidth of 2.21 GHz, an input referred current noise of 11.91 pA/Hz 1/2 , and a power dissipation of 13.5 mW.

A novel sustaining amplifier is designed and characterized for a Si-based MEMS resonator, in implementing a reference oscillator in 180 nm CMOS process. A two port electrical model of the MEMS resonator is used to compute the insertion loss (−76 dB) and phase shift (95°). Total open loop transimpedance gain is achieved as 122 dBΩ with −70°phase shift, at the resonant frequency of 17.22 MHz. This amount of gain is investigated as capable to sustain MEMS resonator's oscillation, in the realization of a cost effective, miniaturized and low power CMOS reference oscillator which oversees on application in clock generation.

“…Typically, the current-mode TIA uses wideband diodeconnected topologies, such as the current mirror, for the input stage to sustain small input impedance and high bandwidth [3]. The basic current mirror circuit has very low input impedance, roughly equal to 1/g m (the small-signal transconductance of the input transistor), and its output current can readily be converted to voltage by means of a resistive load.…”

This work compares two CMOS front-end transimpedance amplifiers (TIA) for use in optical biosensors. They are the shunt-feedback and current-mode circuits, the most widely used for wideband operation. The former consists of a three-stage nested-Miller-compensated (NMC) amplifier in non-inverting mode with a photodiode (PD) bootstrapping and a controlled voltage gain; the latter comprises a wideband common-gate feedback (CGFB) current mirror coupled to a current-to-voltage conversion stage and two common-source gain stages. The simulation results show that the shunt-feedback TIA achieves a maximal gain of 112 dBΩ over a 2 MHz bandwidth, whereas the current-mode TIA has a flat gain of roughly 83 dBΩ over a 115 MHz bandwidth. The overall input rms noise of each circuit was 185pA/√Hz and 53nA/√Hz, respectively, with power consumptions of 0.5 mW and 28.6 mW. It is concluded that the shunt-feedback TIA is a better choice for low to mid-frequency applications.
