A Novel High Performance CMOS Cascoded Operational Amplifier for Process Instrumentation Based Applications

In this contribution, a highly efficient CMOS-based operational amplifier has been presented that uses the circuit arrangement so as to provide an extra bias current into a conventional CMOS differential input signal which is required for high performance of the system. The design of a high performance CMOS operational amplifier (op-amp) with level 3 parameters at 0.2im CMOS technology that makes the use of stacked (cascode) current source techniques. This innovative approach benefits the chances operated by full complementary implementations of well-known sub-circuits, to enhance the speed of such an operational amplifier and to better organize and economize layout generation.
