MOSFET Scaling

intra.ece.ucr.edu

Supply Feature Size CMOS technology has gone through mixed steps of constant voltage and constant field scaling. As a result, field and power density have gone up, but performance gains have been maintained and power per circuit has come down. Fortunately, by physics or by learning, we managed to cope with reliability requirements at higher fields.

necessary to stabilize the input voltage due to the peak current requirement of a switching power supply. The best practice is to use low-equivalent series resistance (ESR) ceramic capacitors. The dielectric material must be X5R or better. Otherwise, the capacitor loses much of its capacitance due to dc bias or temperature.

Though overvoltage and avalanche breakdown are evident, it should be noted that the UIS is a current-driven, transient event. The avalanche current in this case is the same as the peak inductor current indicated by the red dashed line in Figure 1b.
