Question:

Determine the worst-case input offset voltage of the voltage-current converter shown in Fig. 10.23. Assume that the op amps are ideal, that the resistors mismatch by ±0.3 percent and that transistor I_Svalues mismatch by ±2 percent. Neglect base currents. Use SPICE to determine the second and third harmonic distortion in the output for a sinusoidal input drive of amplitude 20 V peak-peak. Assume I_S= 10^ˆ’16A for the transistor and approximate the op amps by voltage controlled voltage sources with a gain of 10,000.
