Abstract:
1. A wideband driver amplifier, comprising: a voltage to current circuit, comprising a first transistor, a second transistor, a third transistor, a fourth transistor and a first capacitor, wherein a drain electrode of the first transistor and a source electrode of the second transistor is coupled together at a first node, wherein a drain electrode of the third transistor and a source electrode of the fourth transistor is coupled together at a second node, and wherein the first capacitor is coupled between the first node and the second node; a passive band-selection filter electrically connected to the voltage to current circuit and configured to filter an output current of the voltage to current circuit; and a current to voltage circuit electrically connected to the passive band-selection filter and configured to receive a filtered output current from the passive band-selection filter, wherein the current to voltage circuit comprises a fifth transistor, a sixth transistor, and a resistor, and wherein the resistor is differentially connected between the fifth transistor and the sixth transistor.
