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.
