The present invention relates to a dynamically-biased baseband current amplifier. The dynamically-biased baseband current amplifier includes: an input interface having a positive output and a negative output; a controller having an output bus; a variable resistor network having a first input, a second input, a control input, a positive output, and a negative output; an amplifier stage having a first input, a second input, a third input, a first output, and a second output; a hybrid differential envelope detector and a full-wave rectifier having a first input, a second input, a third input, and an output; a transconductor having an input, a first output, and a second output; a first variable transistor having a first input, a second input, and a third input; a second variable transistor having a first input, a second input, and a third input; a third variable transistor having a first input, a second input, and a third input; and a fourth variable transistor having a first input, a second input, and a third input. |
