    • 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

  • Low Power Optimization of Bit-Serial Digital Filters
  • 1997
  • Ingår i: Tenth Annual IEEE International ASIC Conference and Exhibit, 1997. Proceedings.. - IEEE--Institute of Electrical and Electronics Engineers Inc.. - 0-7803-4283-6 ; s. 229-232
  • Konferensbidrag (refereegranskat)abstract
    • A new approach to optimize full custom, fixed coefficient bit-serial filters aimed at high sample rate and low power consumption is presented. The idea is to trade the filter order with the coefficient length. To show the results two filters were designed and implemented, one as a minimum order filter and the other as a minimum coefficient filter. Measurements shows that a ten fold increase in sample rate can be obtained at half the power consumption
