An electronic device including in any sequence: a semiconductor layer; and a phase-separated dielectric structure comprising a lower-k dielectric polymer and a higher-k dielectric polymer, wherein the lower-k dielectric polymer is in a higher concentration than the higher-k dielectric polymer in a region of the dielectric structure closest to the semiconductor layer. In one example, motion vectors are determined for a current frame, using sampled pixel information from a reference frame. The controller in the output circuit detects an output voltage and sends detected results to the primary-side coil assembly as a feedback for primary-side coil assembly to regulate the PWM or PFM action of the switch in a specific way to maintain voltage stability. The small bottom electrode contact area reduces the reset current requirement which in turn reduces the write transistor size for each bit. The device possesses multiples of pins serving as contacting points that are capable of treating multiples points on a patients hand. Therefore, the recording operation may be resumed at a user’s desired time.
