MIXER - NIPPON TELEGRAPH & TELEPHONE

Title:

MIXER

Document Type and Number:

WIPO Patent Application WO/2019/203044

Kind Code:

A1

Abstract:

The present invention cancels parasitic capacitance over a wide bandwidth, increases off-impedance, and improves frequency conversion efficiency. A negative capacitance circuit 2 is connected between the drain and the source of a mixer transistor 1. The negative capacitance circuit 2 is thereby connected in parallel to a parasitic capacitance Cp produced between the drain and the source of the mixer transistor 1, and this negative capacitance circuit 2 connected in parallel makes it possible to cancel the parasitic capacitance Cp over a wide bandwidth.
