The presence of a sarcoplasmic reticulum (SR) K+-selective ion-channel has been known for >30 years yet the molecular identity of this channel has remained a mystery. Recently, an SR trimeric intracellular cation channel (TRIC-A) was identified but it did not exhibit all expected characteristics of the SR K+-channel. We show that a related SR protein,(More)
The work presented here proposes local I/Q phase correction and carrier leakage suppression techniques for WiMAX transceivers. Local I/Q calibration was able to compensate for process and supply voltage variations, and the measured I/Q phase errors after calibration are within 3 degrees. The measured carrier leakage after calibration substantially meets(More)
We fabricated a fully integrated WiMAX transceiver in a 90-nm CMOS that can reduce balun and matching network components on an RF module board. Output linearity of up to 12 dBm and a wide variable gain range of 60 dB were achieved using a single-ended signal interface for the PA driver of the transmitter. A combination of a class AB amplifier and a class C(More)
In this paper the analysis of the different types of input impedance matching network for realization of efficient RF energy harvesting circuit. In mobile application like wireless sensors there is issue of long term power backup and charging of batteries. In this paper, there is design to matching circuit compatible for RF energy harvesting by using(More)
We fabricated a multiband transceiver for mobile WiMAX in 90-nm CMOS technology. It operates at three RF bands (2.3/2.5/3.5 GHz) with a large dynamic range. We adopted a double conversion receiver that can switch lower and upper local modes. An image rejection ratio (IRR) tunable single side-band (SSB) mixer was used to achieve over 50 dB IRR. The RCE for(More)
