Abstract:
A wireless receiver with automatic gain control and a method for automatic gain control of a receiving circuit utilized in a wireless receiver are provided. The receiving circuit includes a programmable gain amplifier and a low noise amplifier, and the method includes: comparing a gain code of the programmable gain amplifier with a predetermined code range, wherein the gain code is determined by a frequency signal received through the low noise amplifier; and adjusting a gain of the low noise amplifier when the gain code is out of the predetermined code range.
