This brief analyzes three different mechanisms for injecting a tuning current into the tank of inductively tuned LC-quadrature oscillators. It is shown that, by controlling how the tuning current is injected into the tank, either by magnetic coupling, direct coupling, or the newly proposed partial coupling, a tradeoff exists between tuning range, phase noise, and power consumption.

We demonstrate a new type of adaptive continuous-time linear equalizer (CTLE) based on asynchronous undersampling histograms. Our CTLE automatically selects the optimal equalizing filter coefficient among several predetermined values by searching for the coefficient that produces the largest peak value in histograms obtained with asynchronous undersampling. This scheme is simple and robust and doe... View full abstract»

While RF energy harvesting has proven to be a viable power source for low-power electronics, it is still a challenge to obtain significant amounts of energy fast and efficiently from the ambiance. Available RF power is usually very weak, resulting in a weak voltage applied to a demodulator to drive it into a region of significant nonlinearity. An RF energy harvesting system consisting of a rectenn... View full abstract»

Subthreshold logic has become an attractive option in energy-constrained applications, where the key metric is energy consumption rather than operating speed or silicon area. However, the performance of circuits operating in the subthreshold region is extremely sensitive to the variations in the process, supply voltage, and temperature (PVT). Generally, circuit designers increase the clock period ... View full abstract»
