| 摘要 |
<p>In order to provide a high speed, stable and low voltage logic gate of high applicability by a low-cost BiCMOS process, a BiCMOS logic gate of the invention comprises a pair of MOS transistors (6, 7) with gates supplied with input complementary logic signals and sources coupled and supplied with a constant current from a bipolar transistor (5) controlled by a reference voltage (VCS).</p><p>Voltage swings of the output complementary logic signals are determined by the reference voltage (VCS) and resistance ratio of drain resistor (3, 4) to emitter resistor (8), independent of power supply fluctuation or temparature change.</p> |
