The Class E power amplifier can be turned into an efficient, tuned-input, tuned-output (TITO) oscillator with the addition of a tuned circuit at its gate. The oscillator/amplifier has a power-added ...

As discussed in Part 1 of this series, as the frequency of a single or coupled tuned circuits is increased, the selectivity decreases to the point that there may be insufficient selectivity at the ...

One of the longest-standing debates in neuroscience centers on how preference of individual neurons for sensory stimuli arise in the neocortex. In dedicated areas of sensory cortex, neurons are ...
