signals both with 5 Msample/s are below 3.6% and 5.9% at the output 1 dB compression point. This verifies the PA's capability of amplifying a narrowband modulated signal whose center-tone can be programmed across a large frequency range. The measured BER for transmitting a truly broadband PRBS signal up to 7.5 Gb/s is less than 10 13 , demonstrating the(More)
The ever-increasing demand for higher data rates in communication links has created a need for power amplifiers with large instantaneous bandwidth. Moreover, software-defined radio and smart antenna systems require power stages capable of transmitting at programmable carrier frequencies within a large bandwidth to achieve frequency multiplicity.

This paper presents a scalable and ultrasensitive magnetic biosensing scheme based on on-chip LC resonance frequency-shifting. The sensor transducer gain is demonstrated as being location-dependent on the sensing surface and proportional to the local polarization magnetic field strength &#x007C;B&#x007C;<sup>2</sup> generated by the sensing inductor.

Magnetic spectroscopy allows for characterization of the magnetic susceptibility of magnetic beads across a broad frequency range. This enables differentiation and quantification of multiple beads of varying types concurrently present in the active volume of a sensor's surface. A magnetic spectrometer can be used for multi-probe tagging and identification(More)
