  • Patent number: 11005355
    Abstract: An apparatus is disclosed for improving zero voltage switching (“ZVS”) of a converter circuit such as an active clamp flyback converter. The apparatus includes a first timing circuit acting as the TD(L-H) optimizer, which uses the zero-crossing of the auxiliary winding voltage directly to adaptively vary the dead time. A second timing circuit acting as the TD(H-L) optimizer adaptively varies the dead time with a simple piece-wide linear function as an approximation of the complex optimal equation. A third timing circuit acting as the TDM optimizer contains a charge-pump circuit that adaptively adjusts the ON time of the clamp switch based on the zero-voltage detection of switching node voltage and feed-forwards the input voltage signal to enhance tuning speed so that the correct amount of negative magnetizing current is generated to improve zero voltage switching.

  • Publication number: 20210121685
    Abstract: Optoelectronic retinal prostheses transduce light into electrical current for neural stimulation. A novel optoelectronic pixel architecture is presented comprising a vertically integrated photo junction field-effect-transistor (Photo-JFET) and neural stimulating electrode. Experimental measurements demonstrate that optically addressed Photo-JFET pixels utilize phototransistive gain to produce a broad range of neural stimulation current and can effectively stimulate retinal neurons in vitro. The compact nature of the Photo-JFET pixel can enable high resolution retinal prostheses with a theoretical visual acuity ˜20/60 to help restore vision in patients with degenerative retinal diseases.
