Reducing charge-sensitive-amplifier sensitivity to detector capacitance variations
Nuclear Instruments and Methods, 1967 Abstract A method for reducing the sensitivity of charge-sensitive preamplifiers to detector capacitance variations is described. This method is directly applicable to many existing charge-sensitive preamplifiers with only minor modifications.

Noise optimised charge-sensitive CMOS amplifier for capacitive radiation detectors
IET Circuits, Devices & Systems, 2008 A low-voltage, low-noise, charge-sensitive preamplifier (CSA) for particle tracking using a silicon strip detector was designed. The preamplifier was optimised in terms of the total output noise performance using a noise minimisation technique based on the MOSFET noise small signal equivalent circuit and readout front-end noise optimisation criteria ...

High Efficiency Power Amplifier Based on Envelope Elimination and Restoration Technique [PDF]
, 2010 Due to complex envelope and phase modulation employed in modern transmitters it is necessary to use power amplifiers that have high linearity. Linear power amplifiers (classes A, B and AB) are commonly used, but they suffer from low efficiency especially
