All-pass network

Abstract

A phase-shift network may include a first capacitor connected between a first input node and a first output node, and a second capacitor connected between a second input node and a second output node. Further, a 5 first filter section may be connected between the first input node and the second output node, and a second filter section may be connected between the second input node and the first output node. One or both of the first and second filter sections may include an inductance and a high-pass network. The high-pass network may include third and fourth capacitors and a first inductor. The inductance and third and fourth capacitors may be connected in series between the respective input and output nodes. The first inductor may have a first end connected to an intermediate node between the third and fourth capacitors and a second end connected to a circuit ground.
