摘要

提出了一种采用130nm CMOS本体工艺制造的无电感、可编程输入灵敏度的256倍定模数字分频器。没有电感器和使用的结构允许获得一个小尺寸的芯片。制造的分频器在4.4GHz和6.25GHz时显示出两个最小灵敏度，从1.2V电压电源消耗约5.4mW。分频器的总有效面积为360×115µm2。

A 130nm CMOS tunable digital frequency divider for dual-band microwave radiometer

An inductorless, divide-by-256 fixed-modulus digital frequency divider with programmable input sensitivity, fabricated in 130nm 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 4.4GHz and 6.25GHz consuming about 5.4mW from a 1.2V voltage supply. The total active area of the frequency divider is 360×115 µm2.
