    Abstract: An amplifier system with high gain, compact size, and extended bandwidth is disclosed. The amplifier system includes one or more inputs configured to receive one or more input signals and a pre-driver configured to receive the one or more input signals. The pre-driver may comprise source connected FETs which create a virtual ground and may include inductors which cancel or counter parasitic capacitance of the FETs. The pre-driver amplifies the one or more input signals to create one or more pre-amplified signals, which are provided to a voltage divider network configured to reduce a DC bias voltage of the one or more pre-amplified signals, while maintaining a wide bandwidth range. An amplifier receives and amplifies the output of the voltage divider network to create amplified signals. The amplifier may comprise mirrored FET pairs in a common source configuration and a common gate arrangement.

    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.

    IPC: H03F3/45

    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.
