“…Once the transimpedance has been calculated it is time to take a look at noise. Some previous works like Radovanovic et al [11] and Säckinger [12] demonstrated how the total input referred noise current of the proposed topology can be approximated to…”

“…Furthermore, the effect of increasing Rf on BWi is suppressed by the (1+Ainv) factor, which relaxes the gain-BW trade-off at the expense of power consumption. It is worth noting that increasing Ainv beyond a certain value negatively affects the BW due to the concomitant increase in CT [19].…”

The rapid growth of warehouse-scale datacenters demands high-throughput optical interconnects that can span short-to-medium reach distances (< few kilometers). Microringbased silicon-photonics links with single mode fibers (SMFs) are highly promising for these applications. This paper presents an analysis of microring-based links from the holistic perspective of optical devices, CMOS circuits, and system-level link budget and energy-efficiency simulations. Design considerations and tradeoffs for the receiver, transmitter and the overall link are presented, and comparisons are made to the mainstream multimode vertical-cavity surface-emitting laser (VCSEL)-based links with multi-mode fibers (MMFs). Finally, research opportunities are highlighted for further improving the energy efficiency of single-channel and wavelength division multiplexing (WDM)based silicon-photonics links.

“…When the ETX500 is applied in TIA, efforts should be paid to high-frequency voltage noise gain [16][17][18]. The BF862 has high input impedance, low input voltage noise density (0.8 nV/sqrt(Hz) at 100 kHz) with input capacitance around 9 pF in typical.…”

“…Even the C-TIA is devised for both low input voltage noise and low input current noise, the high-frequency voltage noise gain could dominate the total output noise, as in a normal TIA [16][17][18][19]. In order to enlarge the SNR, much effort has been put onto reducing the voltage noise gain.…”

We report a low-noise, and high-dynamic-range amplifier based on transimpedance amplifier (TIA) for detecting shot noise of 1064 nm laser in quantum optical experiments. Compared with a single junction field effect transistor (JFET) buffered TIA, the electronic noise is effectively 2.8 dB suppressed at the analysis of 2.0 MHz, and 4.0 dB suppressed at 4.0 MHz by means of a JFET bootstrap structure. Under the transimpedance gain of 200 kΩ & 0.5 pF, the measured shot noise at the injected laser power of 51 μW is 12.5 dB above the electronic noise at 2.0 MHz, and 9.8 dB at 4.0 MHz. With adjusting of bias condition of the ETX500 and application of a L-C (inductance and capacitance) structure, the dynamic range is largely boosted from the original 1.52 mW to 11.22 mW. The amplifier meets the requirement of SNR for Bell-state detection in quantum optical experiments. Index Terms-TIA, low noise, large dynamic range, JFET buffering, JFET bootstrap, L-C structure, Bell-state detection, quantum optical experiments.
