CMOS DIGITAL CIRCUITS WITH RESISTIVE SHUNT FEEDBACK AMPLIFIER |
摘要 |
<p>CMOS DIGITAL CIRCUITS WITH RESISTIVE SHUNT FEEDBACK AMPLIFIER A negative shunt feedback amplifier is disclosed for connection to the output node of a complex complementary metal oxide semiconductor logic circuit to increase the performance and reduce the FET device size. A CMOS inverter is coupled to the amplifier to restore the logic levels and to form the logic output. A first embodiment of the invention uses a resistor feedback and a second embodiment of the invention uses parallel N-channel and P-channel FETs to form the feedback impedance. The circuit has application in environments where a logic function requires a large number of FET devices resulting in a large output node capacitance and, thereby slowing the logic speed, as for example in a large DOT-OR circuit or at each output of a FET memory array.</p> |
