Basic EMC (Electromagnetic Compatibility) Technology Advancement for C3 Systems. Volume 1B. Demodulation Radio Frequency Interference Effects in Operational Amplifier Circuits.

Abstract

Since monolithic integrated operational amplifier (op amps) have become important building blocks in today's control and communications systems, a series of investigations have been carried out to determine RFI effects in analog circuits using op amps as active device. The specific RFI effect investigated is demodulations of amplituder-modulated (AM) RF signals in op amp circuits to produce undesired low frequency responses at the AM-modulations frequency. Subsequently, the undesired demodulation responses may be processed in a manner similar to a desired low frequency signal by the low frequency components that follow the order nonlinear transfer function. Keywords include: Electromagnetic compatibility, Electromagnetic interference, Operational amplifiers, Macromodel, Nonlinear response, and Nonlinear transfer function.
