Abstract
In an embodiment, a system includes: an analog-to-digital converter (ADC); a receiver path including a transimpedance amplifier having an output coupled to the ADC; and a controller coupled to the receiver path and configured to, upon detection of a jamming event of the receiver path, cause an increase in a transconductance of the transimpedance amplifier from a first transconductance value to a second transconductance value.

A system comprising:
- an analog-to-digital converter (ADC);
- transmission circuitry;
- a receiver path comprising a transimpedance amplifier having an output coupled to the ADC;
- and
- a controller coupled to the transmission circuitry and to receiver path and configured to, upon detection of a jamming event of the receiver path, cause an increase in a transconductance of the transimpedance amplifier from a first transconductance value to a second transconductance value, wherein the controller is further configured to cause the increase in transconductance before causing the transmission circuitry to transmit a first signal, cause the transmission circuitry to transmit the first signal while the transimpedance amplifier remains at the second transconductance value, disable the transmission circuitry after causing transmission of the first signal, enable the transmission circuitry and cause the transmission circuitry to transmit a second signal with the transimpedance amplifier at the second transconductance value.

A system comprising:
- an analog-to-digital converter (ADC);
- a transmitter path;
- a receiver path comprising a transimpedance amplifier having an output coupled to the ADC;
- and
- a controller coupled to the transmitter path and to the receiver path, wherein the controller is configured to:
- cause an increase in a transconductance of the transimpedance amplifier from a first transconductance value to a second transconductance value,
- simultaneously or after causing the transconductance of the transimpedance amplifier to increase, cause the transmitter path to be enabled, and
- after a first signal begins transmission in the enabled transmitter path, and during transmission of the first signal in the enabled transmitter path, cause the transconductance of the transimpedance amplifier to decrease from the second transconductance value to the first transconductance value.
