“…Sometimes, in a cascade configuration, the total output noise can also be dominated by a noise voltage gained at high frequencies [151][152][153][154]. That is why reduction of the voltage noise gain (dependent on TIA input capacitance) is very important [154][155][156]. For that purpose, the bootstrap structure can be integrated into the cascade TIA (figure 60).…”

This paper reports on recent progress in infrared detection modules that integrate infrared photodetectors, signal processing electronics, optics, heat dissipation systems, and other components in common packages. The integration makes detectors less vulnerable to over-bias, electrostatic discharges, electromagnetic interferences, and other environmental exposures. Additional advantages of integration are improved HF performance, output signal standardization, miniaturization, and cost reduction. Examples are given of detection modules with an infrared detector optimized for uncooled or Peltier-cooled operation in the spectral range of 2 to 16 μm. The paper is mainly based on the authors' experience in the development and fabrication of detection modules at Vigo System S.A.

“…For TIA with large input capacitance, a bootstrap structure is originally intended for input capacitance reduction and for enhancing bandwidth [4,[19][20][21][22][23][24][25][26][27]. The principle of bootstrapping is to apply a buffer amplifier to keep voltages on both sides of the photodiode be the same.…”

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.

“…A/ 2*CA, (5 ' 3) Equation (5.3) gives the frequency response, Af, of a PIN diode [105][106] and C, is the platform capacitance of the PIN. The frequency response of the PIN diode is inversely related to the equivalent resistance, thus, for any wideband operating PIN, the required low R eq will cause high thermal noise, resulting in thermal noise being the dominating noise source [103][104].…”

I thank Dr Goh Cher Hiang for his support towards financing my degree and Miss Goh Lily for her administrative assistance rendered during the duration of the course. Without the support and assistance from them, DSO National Laboratories (DSO)/Satellite Engineering Centre (SEC) and Defence Science & Technology Agency (DSTA), my research would not have proceeded smoothly. I am especially grateful to Prof. Zhong Wende, my supervisor, for his invaluable guidance. This thesis would not have been possible without his effort and time spent on discussing my research work with me. His suggestions and insights allowed me to make progress on my research work. I also thank my family, who has always been my greatest source of encouragement and strength.
