Abstract: A distributed amplifier system comprising an impedance matching network configured to match an input impedance to an output impedance of the signal source, and a DC block configured to block DC components in the input signal. A variable gain amplifier adjusts the gain applied to the input signal based on a gain control signal to generate a gain adjusted signal. An emitter follower circuit receives and processes the gain adjusted signal to introduce gain peaking to create a modified signal. A distributed amplifier receives and amplifies the modified signal from the emitter follower circuit, to create an amplified signal. The distributed amplifier includes a termination network and one or more impedance matching elements configured for gain shaping the amplified signal. The gain peaking introduced by the emitter follower circuit is controlled by a variable current source. The distributed amplifier may be an open collector distributed amplifier.

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: A semiconductor device has an amplifier and common mode suppression (CMS) circuit formed on a common substrate. The CMS circuit has a first input and second input coupled for receiving an input signal and further has a first output coupled to a first input of the amplifier and a second output coupled to a second input of the amplifier to reduce common mode. The CMS circuit further has a ground plane, a first conductive trace disposed over the ground plane and coupled between the first input and first output, second conductive trace disposed over the ground plane and coupled between the second input and second output, and third conductive trace disposed over the ground plane with a first end of the third conductive trace coupled to the ground plane and a second end of the third conductive trace open circuit to form a resonator.
