Low-Distortion Continuous-Time Integrated Filters for Low Frequency Applications

A technique for designing high-linearity continuoustime integrated filters for low frequency applications using transconductance network is presented. With this technique, an area-efficient transconductance network is used to replace the large resistors in low-frequency integrator-based continuous-time filters. The key challenge with this technique is in determining and realizing the appropriat...

High-Order Medium Frequency Micromechanical Electronic Filters

Third-order, high-Q, micromechanical bandpass filters comprised of three ratioed folded-beam resonators coupled by flexural mode springs are demonstrated using an integrated circuit compatible, doped polycrystalline silicon surfacemicromachining technology. A complete design procedure for multiresonator micromechanical filters is presented and solidified via an example design. The use of quarte...

Design of Low Frequency Band Pass Filters for SAR applications

Technologies have advanced rapidly in the field of digital signal processing due to advances made in high speed, low cost digital integrated chips. These technologies have further stimulated ever increasing use of signal representation in digital form for purposes of transmission, measurement, control and storage. Design of digital filters especially adaptive or semi adaptive is the necessity o...

Phase Frequency Detector Using Transmission Gates for High Speed Applications

In this paper a new phase-frequency detector is proposed using transmission gates which can detect phase difference less than 500ps. In other word, the proposed Phase-frequency Detector (PFD) can work in frequencies higher than 1.7 GHz, whereas a conventional PFD operates at frequencies less than 1.1 GHz. This new architecture is designed in TSMC 0.13um CMOS Technology. Also, the proposed PFD a...
