Abstract :
In this contribution we present amplifiers for low noise applications. They have been designed using only N-and P-channel CMOS-compatible junction field effect transistors (JFET) for biasing, amplification, and switching. Using these components a very low noise amplifier system was integrated which consists of a charge sensitive preamplifier and an SC noise filter. Since all active components in this circuit are made of CMOS-compatible JFET´s, the amplifier system is also radiation hardened.
