Abstract
A simultaneous bi-directional (SBD) transceiver includes a main transmit driver, a replica transmit driver, and a series-series-bridged (SSB) tri-impedance network. A pre-driver stage includes parallel delay paths for the main transmit driver and the replica transmit driver, enabling the delay for signals received by the main transmit driver and the replica transmit driver to be independently configured.
Claims26
A simultaneous bi-directional (SBD) transceiver comprising:
- a main transmit driver;
- a replica transmit driver;
- a series-series-bridged (SSB) tri-impedance network;
- and
- wherein a ratio of sizes for the main transmit driver and the replica transmit driver is configured such that the SSB tri-impedance network distinguishes simultaneously transmitted and received signals at an input to a receiver amplifier.
A simultaneous bi-directional (SBD) transceiver comprising:
- a driver stage;
- a pre-driver stage;
- and
- wherein the pre-driver stage comprises parallel delay paths for a main transmit driver and a replica transmit driver, a delay of each of the delay paths being independently configurable;
- and
- the driver stage comprising a series-series-bridged (SSB) tri-impedance network.
A method of performing simultaneous bi-directional communication, the method comprising:
- communicating outbound signals to a series-series-bridged (SSB) tri-impedance network via a main transmit driver and a replica transmit driver;
- receiving inbound signals at an amplifier via the SSB tri-impedance network;
- and
- independently tuning propagation delays of signals received by the main transmit driver and the replica transmit driver.
A simultaneous bi-directional (SBD) transceiver comprising:
- a series-series-bridged (SSB) tri-impedance network;
- a first input path to the SSB tri-impedance network through a first driver;
- a second input path to the SSB tri-impedance network through a second driver;
- and
- the first input path and the second input path comprising propagation delays that are independently configurable from one another.
