Abstract

Provided is a programmable gain amplifier that includes controlled gain steps that dynamically control an output voltage in real-time. The programmable gain amplifier includes a first transistor and a second transistor that includes respective control ports, input ports, and output ports. The programmable gain amplifier also includes a resistor connected to the output ports of the transistors. Further, at least a third transistor is connected to the output ports, in parallel with the resistor. On applying a control voltage to the third transistor and applying an input voltage to the first control port, the second control port is selectively modified by the control voltage to produce a desired output at the first input port and the second input port.
