摘要
This paper describes design of readout circuit destined for NMOS terahertz detectors. The proposed architecture bases on chopper amplifier and instrumentation amplifier concepts. The main goals were to achieve high gain (max. 100 dB) and to enable proper operation with NMOS-based THz detector. For the research needs three different architectures of chopper amplifier have been developed. The designed chip was fabricated in well-known AMS C35 process (350 nm feature size). Another issue described in this paper is dedicated testing environment. At the end a few measurement results are shown.
