Vibrational energy waste generated in the environment from noise, wind power, running water, or water wave action can be scavenged or harvested as a driving force for direct water splitting, thereby forming H2 and O2 by means of PZEC fiber arrays implanted on a substrate. The fiber arrays can...
Using the noise-canceling technique in millimeter-wave band, the LNA achieves a power gain of 12.2 dB, and a NF of 4.6 dB. It consumes 17 mW from a 1 V supply voltage. The chip area is only 0.2 mm2. Finally, a 2.4-GHz LNA with input impedance calibration is realized in 0.18-陳科...
In addition, we design a mechanism to adjust the step size of the adaptive feedback algorithm or inject the probe noise with different magnitude for large magnitude variation input signal. By this mechanism, we can adjust the convergence rate of adaptive feedback algorithm to achieve a higher ...
