Zusammenfassung:An inductorless, divide-by-256 fixed-modulus digital frequency divider with programmable input sensitivity, fabricated in 130 nm CMOS bulk process, is presented. Both the absence of inductors and the architecture used allow to obtain a small sized chip. The fabricated frequency divider exhibits two minima in sensitivity at 4.4 GHz and 6.25 GHz consuming about 5.4 mW from a 1.2 V voltage supply. The total active area of the frequency divider is 360 × 115 ¿m 2 .
