PSK transmission using a circuit with stable and unstable regions

摘要

A circuit to generate antipodal PSK signal for UWB transmissions includes a circuit (502) characterized by a transfer function having alternating stable and unstable regions. By setting the operating point in a stable region or an unstable region, a non-oscillatory or an oscillatory output signal can be produced. A correlator circuit for recovering information from PSK-UWB transmissions is also provided.
