In this paper, a design methodology for low-power MCML based delay interpolating VCOs is presented. The methodology allows a fast and accurate graphical evaluation of the optimum design. It utilizes two closed form expressions for the upper and lower oscillation frequencies of the VCO. An expression of the tuning range is also derived. The effectiveness of the proposed design methodology has been tested by simulating several VCOs in an IBM 0.13 mum CMOS technology.
