Resonance Frequency Readout Circuit for a 900 MHz SAW Device
A monolithic resonance frequency readout circuit with high resolution and short measurement time is presented for a 900 MHz RF surface acoustic wave (SAW) sensor. The readout circuit is composed of a fractional-N phase-locked loop (PLL) as the stimulus source to the SAW device and a phase-based resonance frequency detecting circuit using successive approximation (SAR). A new resonance frequency...
متن کاملSAW Parameters Analysis and Equivalent Circuit of SAW Device
Surface Acoustic Wave (SAW) devices, using interdigital electrodes, play a key role in today’s telecommunication systems and are widely used as electronic filters, resonators, delay lines, convolvers or wireless identification systems (ID tags). During the last three decades, demands set by the expansion of the telecommunication industry and many applications in sensor have resulted in the intr...
متن کاملAn Analog Memory Integrated Circuit for Waveform Acquisition up to 900 MHz
The design and implementation of a switched-capacitor memory suitable for capturing high-speed analog waveforms is described. Highlights of the presented circuit are a 900 MHz sampling frequency (generated on chip), input signal independent cell pedestals and sampling instances, and cell gains that are insensitive to component sizes. A two-channel version of the memory with 32 cells for each ch...
متن کاملA 900-MHz CMOS Bandpass Amplifier for Wireless Receivers
This dissertation describes the design of a CMOS 900-MHz bandpass amplifier that is suitable for RF transceivers. The work employs the state-of-art inductive degeneration techniques to minimize the noise figure and explores the use of lossy spiral inductors in high frequency circuit to realize input matching networks on-chip. A Q-compensation circuit is included to achieve a 25-MHz 3-dB bandwid...
متن کاملA 900-MHz 2.5-mA CMOS Frequency Synthesizer with an Automatic SC Tuning Loop
A 900-MHz phase-locked loop frequency synthesizer implemented in a 0.6m CMOS technology is developed for the Wireless Integrated Network Sensors applications. It incorporates an automatic switched-capacitor (SC) discrete-tuning loop to extend the overall frequency tuning range to 20%, while the VCO gain ( VCO) resulting from the CMOS varactor continuous-tuning is kept low at only 20 MHz/V in or...
