Abstract :
Circuit considerations which are critical for minimizing electromagnetic interference in instrumentation amplifier designs are discussed. A radiofrequency isolation amplifier is used to illustrate the concepts. Component selection and circuit details of the completed device are discussed. It is shown how these affect both amplitude noise and phase noise performance. Active device, capacitor, inductor, resistor, and power supply considerations are discussed
