Dynamic biasing circuit for transceiver

The invention describes a dynamic biasing circuit for transceiver. Embodiments include apparatuses, methods, and systems for providing a dynamic bias voltage to one or more transistors of a transceiver. In embodiments, a transceiver may include receive circuitry and transmit circuitry coupled to a same input/output (I/O) pad. A dynamic biasing circuit may detect a voltage level of a data signal on the I/O pad, and may generate a dynamic bias voltage having a value based on the detected voltage level. In some embodiments, the dynamic bias voltage may be a selected one of a first bias voltage or a second bias voltage. The dynamic biasing circuit may provide the dynamic bias voltage to one or more transistors of the transceiver to protect the transistors from electrical overstress.
