Ultra-low-noise, High-impedance Preamp for Cryogenic Detectors
Introduction: Certain liquid-helium-cooled semiconducting materials make the most sensitive radiation detectors for the far-infra-red region of the spectrum. A few examples are the InSb Putley-mode detector, the Ge photoconductor and the GaAs photoconductor. All three display high dynamic impedance, relatively large bandwidth and very little noise because of their low operating temperature. The...
متن کاملA Low-Noise, Wideband CMOS Charge Sensitive Preamplifier for the High Precision Pixel Detector
A 0.18μm CMOS low-noise wideband charge sensitive preamplifier (CSP) used in a high precision pixel detector was presented in this paper. The preamplifier consists of charge amplification and constant current feedback circuit to accumulate the input charge signal in the feedback capacitor and discharge it by constant current. The open-loop gain of the preamplifier is 52dB at DC, and -3dB bandwi...
متن کاملA Low Noise Cmos Preamplifier for Analog Electro-optical Fibre Links
Several pin-diode preamplifiers have been implemented in bipolar and CMOS processes for electrooptic digital signal transmission. We present a new pin-diode receiver preamplifier optimised for analog signal transmission. The design is based on the active feedback transimpedance circuit which does not require on-chip passive components. The preamplifier has been designed and fabricated in a 0.7μ...
متن کاملAudiofrequency Measurement of Jfet Noise Vs . Temperature in a High Impedance Preamplifier
We describe a high impedance audiofrequency preamplifier and present au-diofrequency noise spectra for 2N4416 and U311 JF'ET's, in a temperature range from room temperature to 80O.K. It is found that optimum noise performance is obtained at-140'K. We present an analysis of some of the sources of noise. Amplifier input capacitance is a.lso measured and discussed.
متن کامل1 Low noise cryogenic electronics : preamplifier configurations with feedback on the bolometer
We developed preamplifier configurations used to readout resistive bolometers such as those based on Neutron Transmuted Doped Germanium thermometers (so called NTD Ge thermometers)[1] or NbSi thin film thermometers [2, 3]. We introduce the impedance regulating preamplifier configuration. This configuration, is compared to previously proposed readout configurations with feedback on the bolometer...
