Abstract: An enhanced electrical circuit can employ conductive fill components that can facilitate providing desirable resistive stabilization of the electrical circuit and other desirable circuit qualities without having to use a physical resistor. The electrical circuit can comprise a transmission line, which can be a microstrip line, that can have defined dimensions. The electrical circuit can comprise respective conductive fill components that can be in proximity to desired sides of the transmission line, wherein the respective conductive fill components can provide the desired resistive stabilization for the electrical circuit. The respective conductive fill components can be separated from, and not in contact with, each other based on respective gaps of a defined size(s) between respective adjacent conductive fill components. The respective conductive fill components can be across a single layer or multiple layers of conductive fill components.

Abstract: An amplifier circuit has a variable gain amplifier including an input receiving an input signal and an open-conduction output, and an output stage including an input coupled to the open-conduction output of the variable gain amplifier and an output providing an output signal of the amplifier circuit. The variable gain amplifier has a first transistor and second transistor each having a control input receiving the input signal. A third transistor has a control terminal receiving a control signal and a first conduction terminal coupled to a first conduction terminal of the first transistor and a second conduction terminal being a first terminal of the open-conduction output. A fourth transistor has a control terminal receiving the control signal and a first conduction terminal coupled to a first conduction terminal of the second transistor and a second conduction terminal being a second terminal of the open-conduction output.

Abstract: Independent control loops for mitigating positive and negative mismatch in differential amplifiers are provided. A method includes comparing a first voltage measured at a positive side output of an emitter follower with a reference voltage, resulting in a first voltage difference. The method also includes comparing a second voltage measured at a negative-side output of the emitter follower with the reference voltage, resulting in a second voltage difference. In addition, the method includes independently controlling the positive side and the negative side of the differential amplifier based on the first voltage difference and the second voltage difference.
