Phase Lead Equalizer

Passive phase equalizer exhibiting positive phase shifts. The magnitude response is flat across the entire frequency range, the value is 0.5 signifying a loss. The phase varies from 180° to 0°, being 90° @ 1 kHz. There is no need for two voltage sources but this was done because a differential probe is not available. The response should be taken from the junction of Cph and Rph to the junction of Rp and Rn. Stacking the two voltage sources and grounding their junction allows the response to be taken by a single-ended probe from the junction of Cph and Rph.
