Abstract: Systems and methods for user-guided automated video production, including video testimonials and other forms of branded video content. A user makes video content selections related to audio and visual graphics for a testimonial. Testimonial requests are then sent inviting others to submit videos. Submitted videos are subsequently processed according to the user's selections to produce branded content with features previously dictated by the user. Branded content without testimonials may also be produced based on user selections.

Abstract: A complementary class AB current mirror circuit with a constant current gain which, when driven by a transconductance amplifier, provides a constant overall voltage gain over a wide range of output current. Such current mirror circuit includes cross-coupled pairs of current mirror circuits, both of which are driven by a common reference current and each of which selectively receives a respective portion of the input signal current. The upper pair of current mirror circuits includes: an input current mirror circuit which generates a drive current for the output stage of the lower pair of current mirror circuits; and an output current mirror circuit which generates the source, or "push," portion of the output signal current.
