A bias circuit for the wireless transceiver is disclosed, which can be used for modulating the gain of the amplifier. The bias circuit comprises a first stage bias unit for receiving a constant current, a control voltage, and a first reference voltage and outputting a first outputting current, wherein the control voltage is used for controlling the value of the first outputting current, and further, the first outputting current can be increased or decreased by representing as an analog form, thus, the gain of the amplifier can be modulated according to t...
We claim: 1. A bias circuit for the wireless transceiver, comprising: a first stage bias unit receiving a constant current, a control voltage, and a first reference voltage and generating a first outputting current and a second outputting current according to said constant current, said control voltage, and said first reference voltage, wherein the value of said first outputting current is controlled by said control voltage, and increased or decreased by representing as an analog form; at least one second stage bias unit connected with said first stage ...
