摘要

一个16通道读出电路能够处理来自薄膜热释电阵列探测器的皮安培范围内的低频调制(1-10赫兹)电流信号，集成在0.7 /spl mu/m CMOS技术中。每个通道由一个高增益(14g /spl ω /)跨阻前置放大器组成，其输入参考电流噪声谱密度在10hz时为1.5 fA//spl径向/Hz。用于解调信号的乘法器跟随前置放大器(斩波频率固定在10 Hz)。最后，信号经过8个周期的积分，然后通过12位a /D转换器进行转换。使用一阶开关电容增量A/D转换器架构，在单个块内实现乘法、集成和A/D转换。

A CMOS readout circuit for pico-ampere thin film pyroelectric array detectors

A 16-channel readout circuit able to process low frequency modulated (1-10 hertz) current signals in the pico-ampere range from a thin film pyroelectric array detector has been integrated in a 0.7 /spl mu/m CMOS technology. Each channel consists of a high gain (14 G/spl Omega/) transimpedance preamplifier having an input-referred current noise spectral density of 1.5 fA//spl radic/Hz at 10 Hz. A multiplier for demodulating the signal follows the preamplifier (chopper frequency fixed at 10 Hz). Finally, the signal is integrated over 8 periods before being converted by a 12-bit A/D converter. The multiplication, the integration and the A/D conversion are implemented within a single block using a first-order switched-capacitor incremental A/D converter architecture.
