Design and characterization of vertical mesh capacitors in standard CMOS
This paper shows how good RF capacitors can be made in a standard digital CMOS process. The capacitors which are also well suited for binary weighted switched capacitor banks show very good RF performance: Q-values of 57 at 4.0 GHz, a density of 0.27 fF//spl mu/2, 2.2 /spl mu/m wide shielded unit capacitors, 6% bottom plate capacitance, better than 3-5% process variation and negligible series inductance. Further, a simple yet accurate method is presented that allows hand calculation of the capacitance value.
