Title:

ELECTRONIC CIRCUIT, DIVIDER, AND WIRELESS DEVICE

Document Type and Number:

WIPO Patent Application WO/2007/029624

Kind Code:

A1

Abstract:

A dividable frequency band is widened without performing variable control of a load circuit. A master stage (101) comprises a differential circuit including a transistor (1) and a transistor (2), a differential circuit including a transistor (3) and a transistor (4), a differential circuit including a transistor (5) and a transistor (6), a load circuit (7) (first load circuit), a load circuit (8) (second load circuit), and a current source transistor (9). The load circuit (7) (first load circuit) includes an inductor (7A) (first inductor), an inductor (7B) (fifth inductor), and a capacitor (7C) (first capacitor). The inductor (7B) and the capacitor (7C) constitute a parallel resonant circuit (first LC parallel resonant circuit), which is connected to the inductor (7A) in series.
