Hi all, This is OT, but just barely. In trying to make a switching amplifier (original design used a PIC for testing), we were using synchronous rectifier. Instead of its complexity, I thought maybe we can use something like Schottky, but much better. Is there such a creature? Basically, we were trying to switch at 80 MHz (!) and still attain better than 90% efficiency (inductors are the enemy!). An ideal diode would've saved few percent, so I guess I'm wondering if there is such a thing as a near-ideal diode (and minimal capacitance, too). We had semiconductor fab at our disposal, so new process would be Ok. However, a commercial product would be the best. Vf = 0 (or less than 0.1 volt) at 1 ampere C = 1 pf or less at 6 volts
