Graphs of relative output magnitude and output phase shift at various frequencies. The resistive load was 60 k\(\Omega \). The complex load was a 58 k\(\Omega \) resistor with a 30 nF capacitor in parallel, both in series with a 2 k\(\Omega \) resistor in the configuration of Fig. 1. Both loads were tested for a constant drive amplitude of 2 mA peak to peak. \(relative\_output = 10*\log _{10}(Amplitude/Amplitude\_at\_10\_Hz)\). The output had minimal attenuation and phase response, especially at lower frequencies
