Abstract:
Generally, in accordance with the various illustrative embodiments disclosed herein, a wideband amplifier includes a direct-current (DC) differential amplifier, an alternating-current (AC) differential amplifier, and a signal combiner circuit. The frequency response of each of the DC differential amplifier and the AC amplifier can be selectively modified by placing the wideband amplifier in one of at least three different operational configurations. The three different operational configurations can be broadly interpreted as a wideband operational configuration, a low-pass operational configuration, and a high-pass operational configuration. The signal combiner circuit operates as a low-pass filter connected to an output terminal of the DC differential amplifier and as a high-pass filter connected to an output terminal of the AC differential amplifier.

Claim (Index 1):
A wideband amplifier comprising:\n a direct-current (DC) differential amplifier configured to provide a first frequency response extending from DC to a first cut-off frequency when the wideband amplifier is placed in a first operational configuration, and extending from DC to a second cut-off frequency that is higher than the first cut-off frequency when the wideband amplifier is placed in a second operational configuration; an alternating-current (AC) differential amplifier configured to provide a second frequency response extending from the first cut-off frequency to a third cut-off frequency when the wideband amplifier is placed in the first operational configuration, and extending from a fourth cut-off frequency that is lower than the first cut-off frequency, to the third cut-off frequency when the wideband amplifier is placed in a third operational configuration; and a signal combiner circuit configured to combine a first output signal of the DC differential amplifier and a second output signal of the AC differential amplifier, the signal combiner circuit comprising a low-pass filter connected to an output terminal of the DC differential amplifier and a high-pass filter connected to an output terminal of the AC differential amplifier.
