Opis:: This paper deals with design of readout circuit dedicated for NMOS-based terahertz detectors. The proposed architecture bases on chopper ampliﬁer and instrumentation ampliﬁer concepts. The main objectives were high gain (max. 100 dB) and proper operation with NMOS-based THz detectors. Three different architectures of measurement ampliﬁer designed for the research project are discussed in this paper. The designed chip was manufactured in AMS C35B4 process (350 nm feature size). Another issue described in this paper is dedicated, non-typical testing environment. At the end a few measurement results are shown.

Opis:: This paper addresses the work performed on development of the readout circuits for FET-based THz detectors. Ultimately, designed readout system is intended to work within the material identification equipment, which targeted to perform the spectral recognition of samples. At the beginning, the short introduction of the THz detection basics and main applications of the THz spectroscopy are presented. Next, the preceding work on single-channel readout circuit is shortly recalled, with a special emphasis on the last design version featuring selective chopper amplifier. This IC became the basis of the complete readout system addressed in next few sections of this paper. Finally, design of novel integrated circuit is presented, incorporating the multichannel readout circuit dedicated for pixel line.

Opis:: This paper introduces a low-noise, low-power amplifier for high-impedance sensors. An innovative circuit using an auto-zeroed architecture combined with frequency modulation to reject offset and low-frequency noise is proposed and analysed. Special care was given to avoid broadband noise aliasing and chopping in the signal path, and to minimize both the resulting equivalent input offset voltage and equivalent input biasing current. The theoretical noise analysis of the proposed topology covers most of the noise sources of the circuit. Simulations show that the input-referred noise level of the circuit is 13.4nV/√Hz for a power consumption of 85µA with a power supply from 1.8V to 3.6V.
