Abstract :
Novel common-mode feedback circuits are proposed for use in pseudo-differential switched-capacitor circuits. They can be implemented by incorporating just four additional capacitors (and switches) for an integrator, and only two additional capacitors for a residue gain amplifier. The circuits are applicable to very low-voltage switched-capacitor stages realized in submicron low-voltage CMOS processes
