CMOS current amplifiers : speed versus nonlinearity
… integrated circuit design using various types of current-mode amplifiers. These circuits are analysed and realised using modern CMOS integration technologies. The dynamic nonlinearities of these circuits are discussed in detail as in the literature only linear nonidealities and static …

Solid-State Impact-Ionization Multiplier
… dissertation presents an innovative solid-state current amplifier based on impact-ionization. Unlike avalanche photodetectors which use the same amplification principle, this device can be integrated with any external current source. A discrete amplifier was built on a silicon surface using …

Delay Line Based Adc And High Frequency Pulse Generation In Electrical Lc Latices
… performed by amplifying the analog voltage (or current) level by a voltage (or current) amplifier. However, due to the device and voltage scaling in the CMOS technology, signal difference amplifications become more challenging to achieve low power consumption with high gain. For a time-domain …
