A dynamic voltage scaling system having time borrowing and local boosting capability, including: a time borrowing circuit and a local boost circuit. The temperature-controlled base has a temperature below the desired temperature of a workpiece. The device is prepared by a combination of foaming, freezing and freeze-drying processes. RF signals may be transmitted via the LWAs, and may include 60 GHz signals. The wave-shaping circuit is constructed so that it is possible to adjust the gain when shaping a waveform according to a control signal CNT to correspond with the gain adjustment of the inverting amplifier.
