摘要：

We present a 32-bit RISC microcontroller having an on-chip DC/DC converter. The chip standby power including the DC/DC converter is reduced to 63muW with a new hybrid regulator scheme in which the microcontroller selects a switching regulator in active mode and a series regulator in standby mode. The achieved standby power corresponds to only about 1 % the standby power with a conventional scheme which always uses a switching regulator.
