Document Type and Number:
Japanese Patent JP4089839
Kind Code:
B2
Abstract:
A differential amplifier circuit comprises a first differential transistor circuit, a grounded base transistor circuit and a second differential transistor circuit. A pair of transistors of the second differential transistor each produces a current based on an emitter voltage of each of a pair of transistors of the grounded base transistor circuit for cancelling non-linear components of transistors of the first differential transistor circuit. The currents produced by the second differential transistor circuit are each cross-added to an alternating current component of each of the first differential transistor circuit at a collector of each of the pair of transistors of the grounded base transistor circuit. Non-linear components of the first differential transistor circuit are thus cancelled out.
