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.

摘要： There is provided a variable gain mixer capable of controlling a gain at a low source voltage in a wide range without additional current consumption.The mixer includes: mixers constructed with variable gain amplifiers having two transistor pairs Qp+/Qp− and Qn+/Qn− to have a predetermined gain by using LO+ and LO− signals; and LO bias circuits connected to have bias voltages different from each other with respect to the LO+ and LO− signals of the mixers and share an input signal.Accordingly, by integrating the variable gain amplifiers into the mixers, a gain change can be obtained at a low source voltage in a wide range without connecting a number of variable gain amplifiers. In addition, by properly applying the LO signals used in the mixers, the gain change can have a linearity in dB characteristic
