Abstract：
 The invention belongs to the area of the analog signal processing and the communication technique related tot the DC level translator. The translator composed of the PMOS tubes M1 and M2 possesses the connecting relation as follows. The input signal Vin is connected to the grid of the PMOS tube M1. The drain pole of the PMOS tube M1 is connected to the ground. The source pole of the PMOS tube M1 is the output Vout, meanwhile the node is connected to the drain pole of the PMOS tube M2. The source pole of the M2 is connected to the power source Vdd. The grid of M2 is connected to the bias voltage VB. The characteristics are that the M2 works in the weak anti configuration area. The bias voltage VB is less than the threshold voltage of the M2 tube.
