The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

Abstract – This paper presents the cross-coupled MOS resistor circuits. The circuits consist of two internal pairs of NMOS and PMOS transistors, and their critical width and length parameters regulate the drain current, transconductance, and output drain resistance. Consequently it determines the output resistance of the circuits. The cross-coupled MOS resistor circuits can be used in multiplic...
