High Performance Low Voltage Analog Design Using Self Cascode Structures
Jasdeep Kaur, S.S. Rajput and Nupur Prakash
A low voltage high performance gain boosting self cascode structure is presented. This has been used to build a level shifted low voltage self cascode current mirror which has output resistance of 300 KΩ and bandwidth of 3.3 GHz with standard resistive and capacitive compensation. Modular self cascode current conveyor architectures are implemented using the current mirror, having voltage transfer bandwidth of 195 MHz and current transfer bandwidth of 203 MHz. These structures have been verified using P-spice simulations for 0.13 μm CMOS technology with level 7 parameters.
