1. Discuss the internal noise sources that are present in a typical signal source and amplifier circuit, and describe their effects.
2. The company currently has a low noise amplifier circuit for which the LM4136 and the LMC6034 operational amplifiers are contenders. Determine the total noise generated for each and so recommend the best.
Some circuit details are as follows.
Signal source output impedance = 5k0
maximum input signal = 100 mV
bandwidth = 100 Hz to 10 kHz
system gain = 20 dB
Operating temperature = 17 0C
Resources
The data sheets for both amplifiers are attached, but may also be found in the National Semiconductor Operational Amplifiers Data sheets.
