  • Abstract
    In this paper a simple opamp input stage architecture with programmable rail-to-rail constant-gm is presented. The constant-gm is achieved by processing signal, rather than DC, currents. As a result, the architecture is universal in that it can be implemented in any complementary VLSI technology and it functions regardless of transistors operating region. A MOS implementation is discussed and is shown to operate in both weak and strong inversion, resulting in a programmable gm, or unity gain frequency, over a very wide range
