摘要

模拟VLSI传感器的工作受到人造光源镜面反射引起的乘性噪声的显著影响。本文描述了一种拟议的乘性噪声消除(MNC)架构和电路的实现。该电路已应用于某运动检测芯片，仿真结果表明，该电路的信噪比提高了约10倍。

Multiplicative noise cancellation (MNC) in analog VLSI vision sensors

The operation of analog VLSI sensors can be significantly affected by multiplicative noise caused by specular reflections of light from artificial sources. The paper describes the implementation of a proposed architecture and circuits for multiplicative noise cancellation (MNC). The circuit has been used in a motion detection chip, and simulation results indicate about ten times improvement in the signal to noise ratio.<>
