This paper presents development of the integrated multi-channel readout circuit targeted to support the pixel-line of FET-based THz-detectors. The authors discuss architecture details and design techniques used to address the most important issues related to the processing of very small, low-frequency signals. The effectiveness of the 1/f noise component minimization and crosstalk cancellation, proven...
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...
