The present invention provides a receiver with low power consumption. The receiver with low power consumption adjusts the gain of the programmable gain amplifier based on the automatic gain controller and further optimizes the gain bandwidth product by current-adjusting unit. The current-adjusting unit thus adjusts the current provided for the programmable gain amplifier, e.g. operational amplifier. Therefore, the gain bandwidth product of the programmable gain amplifier is optimized and the power consumption of the receiver is effectively decreased.
