Operational Amplifier Noise For the circuit shown below, where v,-25, and the source is ideal, except for thermal noise in the source resistance, find the noise figure, and the signal to noise ratio at both the input to the amplifier and the output. (Note: Assume the input noise voltage for an OP-77 as en 10nV/VHz and the input noise current as in 0.1pA/VHz) 1K Vout In F 1 K. 10K Figure 1 Operational Amplifier Noise Circuit
