<p>Disclosed herein is a bias voltage stabilizing circuit which comprises a dc voltage source, a first voltage drop circuit (10b) having a first diode (11), and a second voltage drop circuit (10c) having a second diode (13). The first voltage drop circuit and the second voltage drop circuit are electrically series-connected to each other and electrically parallel-connected to the dc voltage source. Resistors (12,14) are electrically connected to at least one of the first voltage drop circuit and the second voltage drop circuit in series with either the first diode or the second diode. A closed loop is formed by the dc voltage source, the first diode, the second diode and the resistors. The voltage at a point where the first voltage drop circuit and the second voltage drop circuit are electrically connected to each other, is used as a bias voltage. <IMAGE></p> |
