<p>A low power level converter (20), for converting from one logic level to another, includes six transistors (21 - 26). Two transistors (23 and 25) are connected to form a current mirror. A power supply voltage is provided to both sides of the current mirror through a third and a fourth transistor (22 and 26). The third and fourth transistors receive complementary signals VI and VI. A fifth transistor (21) is connected between the third transistor and the power supply, and a sixth transistor (24) is connected across the current mirror. An output signal, provided at the mirror side of the current mirror, is fed back into the converter at the control electrodes of the fifth and sixth transistors and utilized to prevent a constant undesirable DC current from flowing between the power supply voltage terminals, thereby reducing the power consumption of the converter. <IMAGE></p> |
