I had to add V2 and R4 as shown in Figure 2 to serve as an external stimulus to convince the Bode Plotter to do its thing. The Bode Plotter would not accept the oscillator’s own oscillation as the circuit excitation. However, when I tried to use the Bode Plotter on the oscillator circuit itself, there was no response, even though the oscillator was working and delivering signal. The signal source V1 provided the circuit excitation required by the Bode Plotter tool to get that instrument to function. Using a Bode Plotter on the passive component network alone, I saw what I was hoping to see: a sharp peak in the transfer function at the correct frequency-in this case at approximately 1.6MHz. 《MOTIX™ Multi-MOSFET Driver: Best-in-Class Solution for DC Motor Control》□To control up to eight half-bridges with one packaged deviceįigure 1 An unsuccessful analysis attempt.
