Abstract

Signal processing for photodetectors and CCD imagers requires application of sample and hold amplifiers or double correlated sample and hold amplifiers that it is necessary for the noise suppression. The technology permits to integrate the microwave n-p-n transistors with low level noise junction field-effect transistors and Schottky diodes in one silicon chip. This gives an opportunity on creation of a base chip for construction high-speed microcircuits of sample and hold amplifiers containing amplifier modules and analog switch modules. At development of a base chip these two main functional modules were designed. The amplifier module consists of three cascades with the first cascade on a p-junction field-effect transistor. An analog switch module consists of the Schottky diode bridge and the control circuit on high-speed bipolar transistors. The result of the development and research is high speed double correlated sample and hold amplifiers for CCD imaging systems.
