Abstract: An apparatus comprising a first circuit and a second circuit. The first circuit may be configured to generate an output signal oscillating at a frequency in response to a first control signal and a second control signal. The second circuit may be configured to generate the second control signal in response to (i) an input voltage and (ii) the output signal. The second circuit (i) generates the second control signal by comparing a peak voltage of the output signal to the input voltage and (ii) adjusts an amplitude of the control signal in response to the comparison.

Abstract: In a high frequency mode a multiphase voltage-controlled oscillator (VCO) generates a first plurality of signals where each has the desired frequency and a different phase. A phase interpolator generates the signal at the desired frequency and the desired phase using a first plurality of signals. In a low frequency mode the VCO generates a second plurality of signals where each has a frequency which is a multiple of the desired frequency and a different phase. A multiphase frequency divider generates a third plurality of signals by dividing the frequency of the second plurality to the desired frequency while maintaining a phase relationship with the second plurality of signals. The phase interpolator generates the signal at the desired frequency and the desired phase using the third plurality.

Abstract: An apparatus comprising an amplifier, a first resistor and a second resistor. The amplifier (i) comprises a first transistor and a second transistor and (ii) may be configured to generate an output signal in response to an input signal. The first resistor may be connected between an emitter of the second transistor and a signal ground. The second resistor may be connected between the emitter of the second transistor and a base of the first transistor. A gain of the amplifier may be adjusted by varying a value of the first resistor and a value of the second resistor.

Abstract: A coil integrated semi-conductor device and method of making the same is disclosed. First to third metal layers are in sequence formed on a semi-conductor device. The first and third metal layers of equal width are connected to each other through contact holes, to define a hollow region which is filled with the second metal layer disposed centrally therein and a circumferential region surrounding the second metal layer. The first and third metal layers are used as a coil and the second metal layer is used as a core of magnetic material. The circumferential region surrounding the second metal layer is filled with different dielectric layers. According to the invention, a coil capable of exerting the magnetic field effect can be integrated in a semiconductor chip. This makes it possible contemplation of compactness, integration and preciseness of devices in the form that the coil is wound around the care.

Abstract: The present invention relates to a level translator which translates TTL level signals to ECL level. The translating speed is enhanced by making the input circuit of the level translator which receives the TTL data signal composed of an emitter coupled pair such that the circuit does not act in saturation mode. Also, by designing the circuit to make current flow from the pull-up transistor of the TTL transfer through the resistance of the present invention when the TTL data is high level, and to make current flow through the pull-down transistor of the driving TTL circuit into the TTL to ECL level translator when low level, the present invention makes the time delay from the driving TTL circuit to the ECL receiving circuit very small.
