Title:
TEMPERATURE COMPENSATION BIAS CIRCUIT AND POWER AMPLIFIER
Document Type and Number:
WIPO Patent Application WO/2023/231527
Kind Code:
A1
Abstract:
A temperature compensation bias circuit (100), comprising a third resistor (R3), a fourth resistor (R4), a fifth resistor (R5), a sixth resistor (R6), a seventh resistor (R7), a second capacitor (C2), a third capacitor (C3), a fifth capacitor (C5), a fifth transistor (T5), a sixth transistor (T6) and a seventh transistor (T7). A power amplifier using the temperature compensation bias circuit (100). The temperature compensation bias circuit (100) and the power amplifier have a small impact on a bias point in a radio-frequency operating state, such that the power amplifier has a good temperature compensation effect and high linearity.
