A Custom Digital Intermediate Frequency Filter for the American Mobile Telephone System
Author
Summary, in English
A digital filter for intermediate frequency filtering in mobile communication systems is presented. The purpose of the work is to show an alternative to the analog filters which are used in most of today's heterodyne receivers. Bit-serial arithmetic is applied on a twelfth-order wave digital lattice filter algorithm. The paper also shows a method for retiming such algorithms. The power consumption in two fabricated prototypes is compared. By customizing the library cells, the power consumption has been reduced significantly. In the low power prototype, the power dissipation is 8 mW using 3 V supply voltage. The prototype is a 10 MIPS design fabricated in a 0.8-μm standard two-metal-layer CMOS process
