A resolver excitation signal generator includes a source configured to generate a sinusoidal input signal and an inverting amplifier circuit. The inverting amplifier circuit has an input connected to the source to receive the sinusoidal input signal and an output lacking a transistor stage. The inverting amplifier circuit is configured to amplify the sinusoidal input signal to generate at the output of the inverting amplifier circuit an excitation signal in the form of an amplified version of the sinusoidal input signal for a resolver.
