International Classification:

H03G003/30
H03F001/22

US Classification:

330282000, 330284000, 330311000

Abstract:

A variable gain control amplifier () and method provides a substantially constant input impedance and output impedance, and provides a substantially constant noise figure and third order harmonic. The variable gain control amplifier () includes an amplifier stage including at least a first intermediate fixed gain stage () operative to produce a first intermediate signal () in response to the input signal (). The variable gain control amplifier () further includes at least a second intermediate fixed gain stage () operative to produce an output signal () in response to the first intermediate signal (). A feedback circuit () is operative to produce a gain control signal () in response to the output signal (). A gain control circuit () is coupled to the at least first intermediate fixed gain stage () and the second intermediate fixed gain stage (), and receives the gain control signal () to control an amplitude of the intermediate signal ().

Abstract:

Bias circuits and methods for silicon-based amplifier architectures that are tolerant of supply and bias voltage variations, bias current variations, and transistor stack height, and compensate for poor output resistance characteristics. Embodiments include power amplifiers and low-noise amplifiers that utilize a cascode reference circuit to bias the final stages of a cascode amplifier under the control of a closed loop bias control circuit. The closed loop bias control circuit ensures that the current in the cascode reference circuit is approximately equal to a selected multiple of a known current value by adjusting the gate bias voltage to the final stage of the cascode amplifier. The final current through the cascode amplifier is a multiple of the current in the cascode reference circuit, based on a device scaling factor representing the relative sizes of the transistor devices in the cascode amplifier and in the cascode reference circuit.
