Complex low-pass filters
Zero-if transceivers suffer from the imbalance of the I and Q paths. By using a complex low-pass filter topology instead of a conventional pair of real low-pass filters, this imperfection can be reduced. Both analytical and numerical analysis show that the proposed technique is significantly more robust to circuit imperfections than the traditional architecture.
متن کاملDesign of Low Power Digital Filters
In this paper we propose an efficient approach to design high-speed digital filters with low power consumption which is based on power supply voltage scaling and exploiting the excess speed that may be obtained by using maximally fast recursive filter structures. We also discuss several techniques to increase and obtain the maximal sample rate for recursive structures based on frequency masking...
متن کاملMicromechanical filters for miniaturized low-power communications
With Q’s in the tens to hundreds of thousands, micromachined vibrating resonators are proposed as IC-compatible tanks for use in the highly selective filters of communications subsystems. To date, bandpass filters consisting of spring-coupled micromechanical resonators have been demonstrated in a frequency range from HF to VHF. In particular, two-resonator micromechanical bandpass filters have ...
متن کاملA graph search algorithm: Optimal placement of passive harmonic filters in a power system
The harmonic in distribution systems becomes an important problem due to an increase in nonlinear loads. This paper presents a new approach based on a graph algorithm for optimum placement of passive harmonic filters in a multi-bus system, which suffers from harmonic current sources. The objective of this paper is to minimize the network loss, the cost of the filter and the total harmonic disto...
متن کاملOptimal Systolic Block Size for Low Power High Speed Digital Filters Based on 3-port Adaptor
Abstarct-Allpass digital lters are major building blocks in many digital lter architectures. In this paper an optimal pipelined architecture for a 2nd order allpass section based on 3-port adaptor is proposed. The architecture has been shown to improve the lter overall performance in term of power-area-speed by 3 times using 1 m CMOS standard cell design and by 5.4 times using custom cells. Giv...
