Abstract:
1. A differential cascode amplifier comprising: two transistors wired to form a cascode circuit in a first and second branch of the differential cascade amplifier; and a cross-compensation having at least one pair of capacitors, wherein, for compensating a base-emitter capacitance of each of the first and second branch, one capacitor of the pair is equal to a base-emitter capacitance of the associated branch, and/or wherein, for compensating a base-collector capacitance of each branch, one capacitor of the pair is equal to the base-collector capacitance of the associated branch, and/or wherein, for compensating a gate-source capacitance of each branch, one capacitor of the pair is equal to the gate-source capacitance of the associated branch, and/or wherein, for compensating a gate-drain capacitance of each branch, one capacitor of the pair is equal to the gate-drain capacitance of the associated branch.
