1 GHz Low-Noise Hybrid Preamplifier for Optical Detection

A 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...

Université De Montréal Cmos Low Voltage Preamplifier Based on 1/f Noise Cancellation

1 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...

Low-noise preamplifier with input and feedback transformers for low source resistance sensors

We describe the design, schematics, and performances of a very-low-noise, low-frequency preamplifier. It operates in the 5 Hz-100 kHz range and offers an input equivalent voltage noise density as low as 65 pV/ ,/I%; the current noise increases with frequency and settles to about 1.5 pA/ @ at 100 kHz. The amplifier uses input and feedback signal transformers and operates in full differential mod...

A 1.8 GHz CMOS Low-Noise Amplifier

A 1.8 GHz low-noise amplifier has been designed and fabricated in a standard 0.35 pm CMOS process. Measurement results indicate that the amplifier has a forward gain (S21) of 10.5 dB and a noise figure of 3.94 dB, while consuming 40 mW from a 2.5 V supply.
