In one embodiment, a semiconductor package comprising a metal base coupled to one or more pins, a semiconductor body having a top side and a bottom side, the top side comprising an integrated circuit and one or more metal surfaces for coupling the integrated circuit to the one more pins with one or more bonding wires, the bottom side non-positively coupled to the metal base, a disk having a top area and a base area, the base area coupled to the top side of the semiconductor body and at least partially covering the integrated circuit, the disk being electrically insulated from the semiconductor body, and a plastic compound completely enclosing the one or more bonding wires, and at least partially enclosing the top side of the integrated circuit, the top area of the disk, and the one or more pins.

Semiconductor package

A d.c. signal controlled oscillator includes a frequency-determining network having a control input and a modulation input. A phase regulating loop includes the oscillator and components that provide a control signal to the control input. A circuit apparatus for driving the oscillator includes a modulation generator that provides a modulation signal to the modulation input, and a circuit arrangement that autonomously generates a signal depending on and representing a slope of the modulation and provides this slope signal to the modulation generator, which generates the modulation signal dependent on the slope signal. A method of operating the oscillator involves switching a frequency divider successively to two different frequencies, respectively sampling and holding the two different arising control voltages, forming a difference between the two control voltages, and activating the modulation generator so that a modulation swing of the modulation signal is determined by this difference between the control voltages.

An integrated circuit layout complete with a bus logic unit connected to a data bus. The data bus includes at least one activation line for an activation signal, making it possible--via the data bus--to activate the bus logic unit for data transmission. A controllable power supply unit is provided with a control input connected to the activation line and serves to feed an operating current to the bus logic unit. The operating current is reduced by the activation signal when the bus logic unit is deactivated.
