<p>A bias circuit comprises first and second transistors (MN1,MN2) each of which receives a common gate voltage; a load circuit (MP1,MP2) that is connected to the drains of the first and second transistors; a control circuit (MP3,MN3) that generates a control signal based on a signal from the load circuit; a current source (MN4) that is controlled by the control signal and connected commonly to the first and second transistors; and a first impedance circuit (R) that is connected between the second transmitter and the current source.</p> |
