摘要: 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.

摘要: A band gap reference voltage generator with low working voltage is disclosed. The band gap reference voltage generator can stably operates that the unexpected balance status does not occur due to the manufacturing process inaccuracy or the offset voltage. The band gap reference voltage generator comprises a thermal voltage generation circuit, a voltage level optimizing circuit and a band gap reference voltage generating circuit. The thermal voltage generating circuit provides a first voltage and a second voltage. The first voltage is for generating a current component increased with temperature rising. The second voltage is for generating a current component decreased with temperature rising. The voltage level optimizing circuit optimizes the voltage level of the second voltage to generate a third voltage. The band gap reference voltage generating circuit generates the reference voltage with a specific voltage level corresponding to the first voltage and the third voltage irrelevant with the temperature.
