A very fast monolithic charge sensitive preamplifier using HF2CMOS technology featuring less than 45mW power dissipation for a 5V max imum output voltage swing, with a slew rate about 700Y/~csec for 150pF input capacitance (~ 7nsec rise time), has been realized . A front-end set up for the read out of more detectors and the shaping of the signal with a 20nsec RC-CR filter employing only monolit...

The paper describes studies dealing with problems of the receive coil for NMR scanner connected via a preamplifier with high input impedance. Behaviour of the coil with preamplifier after pulses of RF signal was studied and an equation was derived and verified for investigation of it. The theory is demonstrated on a one-turn surface coil with rather large dimensions. Some parameters of a coil a...

The detection of an optical signal using a photonic mixer device (PMD) as an alternative to the PIN photodiode for a high-speed infrared link is discussed. The PMD, at its linear range, is characterized as a correlator detector. The functionality of this PMD for a better Signal-to-Noise Ratio is described. With an improved mixing efficiency and photosensitive area, the PMD will replace the use ...

This note describes the Front-End Electronics for the ICARUS Experiment, in particular the Preamplifier structure and the strategy foreseen to digitize the signals to achieve the required dynamic range.
