Abstract

This paper describes a new sub-volt differential difference current feedback operational amplifier. A floatinggate technique is used to reduce the supply voltage requirement. Differential difference voltage can be easily obtained by using floating-gate technique. Simulation results using TSMC 0.18 μm n-well CMOS technology are given. From a 0.8 V supply, the proposed circuit consumes 20 μW of static power. Universal biquadratic filter using proposed active building block as active element was presented as an example application.
