Opis:: This paper presents the design of a chopper stabilized current mode instrumentation amplifier and analyzes the performance limitations imposed by chopping technique in detail. The amplifier targets to be the read out circuitry of a high precision temperature sensor. Since the required bandwidth in this kind of applications is very low, nested chopping technique is used to provide continuous offset reduction and eliminate 1/f noise. The amplifier is designed in 0.18 μm CMOS process. The resulting input referred noise is 20 nV/√ Hz, the offset is 582 nV and the CMRR exceeds 110 dB. The power consumption of the total design is 420 μW.

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.
