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.
