—A new input matching method making use of shunt–shunt feedback capacitance is introduced. Based on the new input matching method, reconfigurable SiGe low-noise amplifiers (LNAs) by varying shunt–shunt feedback capacitance are proposed. Two approaches are used to vary the shunt–shunt feedback capacitance. One approach is to switch between two different bias(More)
A quick wireless label-free detection of disease-related C-reactive proteins (CRPs) using a 200-microm-long microelectromechanical systems (MEMS) microcantilever housed in a 7 x 7 mm(2) reaction chamber with a safe reusable feature is reported. The assay time ranges from about 30 min to 3 h, depending on accuracy. The deflection of the microcantilever due(More)
—A 5.0-GHz-band monolithic direct-conversion receiver front end employing subharmonic mixers (SHMs) is demonstrated in 0.18-m CMOS technology. Instead of using transistors as transconductors, the SHMs adopt on-chip 1:4 transformers to achieve voltage gain, and hence, excellent local-oscillator self-mixing suppression and good linearity can be obtained.(More)
