摘要： A method of making an inductor and the inductor. The inductor comprises a plurality of serially connected transistors at least partially formed in a substrate, preferably a silicon on insulator substrate, and comprises a gate common to the plurality of transistors. The plurality of transistors, transistor contacts, and electrical interconnects form the coil of the inductor and the gate common to the plurality of transistors forms the core of the inductor. Two inductors of the invention are magnetically coupled to form a transformer of the invention. A control transistor is serially connected to the primary inductor of the transformer. The control transistor is gated by a periodic output signal of a ring oscillator. An actuation and a deactuation of the control transistor allows the current in the primary coil to vary creating a changing magnetic flux in the primary and secondary cores and inducing a fluctuating current in the secondary coil.

摘要： A highly efficient compact multiple output voltage generation circuit is designed for use in integrated circuit devices such as DRAMs which require multiple internal voltage supplies for optimum performance. An oscillator is connected to a primary coil of a microtransformer. The microtransformer secondary coil has multiple taps one of which is connected to ground. A second transformer tap is connected to a transformer output node. The oscillating transformer output signal is capacitively coupled to a voltage rectifier. The input to the rectifier is biased to one diode drop below Vcc. The output of the rectifier is an internal supply voltage greater than ground. Another transformer tap is connected to a negative oscillation output node. The negative oscillating signal is rectified to produce a negative internal supply voltage. The voltage generation circuit operates effectively at low Vcc input levels where capacitor based voltage pumps often fail. The circuit is compatible with CMOS manufacturing processes.
