Abstract

The invention provides an adjusting circuit used for adjusting current consumption. The adjusting circuit comprises at least two paths of matching circuits and a switching switch. The at least two paths of matching circuits are used for matching different input signals, so that current consumption can be reduced. The switching switch is connected with the at least two paths of matching circuits and is used for selectively turning on one matching circuit of the at least two paths of matching circuits according to different input signals. Each path of matching circuits comprises a transmission line and a variable capacitance diode. The transmission lines are connected with the switching switch and used for adjusting the phase angle, so that the phase angle falls in a preset quadrant of a Smith chart; the variable capacitance diodes are used for further adjusting the phase angle so that the phase angle can be located at a preset position in the preset quadrant. The invention also provides an optimizing circuit. In the adjusting circuit and the optimizing circuit, different input signals can be transmitted in the corresponding matching circuits, so that current consumption in the circuits is greatly optimized.

Description

technical field [0001] The invention relates to a signal adjustment circuit, in particular to an adjustment circuit and an optimization circuit for optimizing current consumption. Background technique [0002] A Long Term Evolution (LTE) system is widely used in some communication products such as mobile phones. In the LTE system, current consumption is one of the main performance indicators, and people pay great attention to how to reduce the current consumption to reduce power consumption. However, there are many factors affecting the current consumption in the system, among which the use of the power amplifier is the biggest factor affecting the current consumption, and it takes a lot of time to find the optimal load pull value of the power amplifier. Contents of the invention [0003] In view of this, it is necessary to provide an adjustment circuit for optimizing current consumption and an optimization circuit, so as to reduce the current consumption in the circuit a...
