US 12,627,263 B1 · Systems and methods for low voltage and low power transimpedance amplifier (TIA) design

Abstract

In part, exemplary systems and methods are disclosed for maintaining low voltage and low power in a transimpedance amplifier (TIA). One system includes a sensor (e.g., a photodetector); the TIA; and a dummy TIA. The TIA includes a front end stage, a detector, and a back end stage. In some embodiments, the front end stage is configured to receive a current output from the sensor. In many embodiments, a reading of the detector is used to monitor the current output from the sensor. The back end stage is configured to convert the current to an output voltage in various embodiments. The dummy TIA is coupled to the sensor and diverts the current output from the sensor when the current exceeds a predetermined threshold in some embodiments.

Dependent claims

A system for maintaining low voltage and low power in a transimpedance amplifier (TIA), the system comprising:

a sensor;
a main TIA comprising a front end stage, a detector, and a back end stage,
wherein the front end stage is configured to receive a current output from the sensor,
wherein a received signal strength indicator (RSSI) at the detector is used to monitor the current output from the sensor,
wherein the back end stage is configured to convert the current output to an output voltage;
and
a dummy TIA coupled to the sensor, wherein the dummy TIA diverts the current output from the sensor when the current output exceeds a first predetermined threshold, and wherein comparing the RSSI to a second predetermined threshold indicates whether the current output exceeds the first predetermined threshold.
