Chopper Stabilization

This paper proposes a low noise readout integrated circuit (IC) with a chopper-stabilized multipath operational amplifier suitable for a Wheatstone bridge sensor. The input voltage of the readout IC changes due to a change in input resistance, and is efficiently amplified using a three-operational amplifier instrumentation amplifier (IA) structure with high input impedance and adjustable gain. Furthermore, a chopper-stabilized multipath structure is applied to the operational amplifier, and a ripple reduction loop (RRL) in the low frequency path (LFP) is employed to attenuate the ripple generated by the chopper stabilization technique. A 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) is employed to convert the output voltage of the three-operational amplifier IA into digital code. The Wheatstone bridge readout IC is manufactured using a standard 0.18 µm complementary metal-oxide-semiconductor (CMOS) technology, drawing 833 µA current from a 1.8 V supply. The input range and the input referred noise are ±20 mV and 24.88 nV/√Hz, respectively.

A readout integrated circuit (ROIC) of infrared focal plane array (IRFPA) with low power and low noise is presented in this paper. It consists of a 384 × 288 pixel array and column-level A/D conversion circuits. The proposed system has high resolution because of the odd–even Analog to Digital Conversion (ADC) structure, containing correlated switches design, multi-Vth amplifier design and high speed high resolution comparator design including latch-stage. Designed and simulated in 0.35-μm CMOS process, this high performance ROIC achieves 81.24 dB SNR at 8.64 KS/s consuming 98 mW under 5 V voltage supply, resulting in an ENOB of 13.2-bit.

High Uniformity

Infrared focal plane arrays (IRFPA) suffer from inherent low frequency and fixed patter noise (FPN). To achieve high quality infrared image by mitigating the FPN of IRFPAs, a novel low-noise and high uniformity readout integrated circuit (ROIC) has been proposed. A correlated double sampling (CDS) with single capacitor method has been adopted in the ROIC design which can effectively reduce the FPN, KTC and 1/f noise. A 4×4 experimental readout chip has been designed and fabricated using the SMIC 0.18 μm CMOS process. Both the function and performance of the proposed readout circuit have been verified by experimental results. The test results show that the proposed ROIC has a good performance in practical applications.
