摘要： A reference signal generator includes an integrated circuit substrate having a semiconductor resonator therein. The resonator includes an inductor extending adjacent a first surface of the integrated circuit substrate. A vertically-stacked composite of at least first and second electrically insulating dielectric layers is provided on the integrated circuit substrate. The vertically-stacked composite covers a portion of the first surface, which extends opposite the inductor. A first electrically conductive shielding layer is provided on a portion of the second electrically insulating dielectric layer extending opposite the inductor. The first electrically conductive shielding layer may encapsulate exposed portions of the first and second electrically insulating dielectric layers. The shielding layer may operate as an electromagnetic shield between the inductor and an external structure, such as an integrated circuit package, and also shield against environmental contamination (e.g., external moisture penetration).

摘要： In a frequency modulation radio receiver with direct conversion, a local oscillator signal is generated having a frequency within a preselected frequency range and the frequency is varied in response to a variable low frequency signal; the local oscillator signal is mixed with a received signal to provide a baseband signal. The variable low frequency signal is generated by a controlled oscillator in inverse relationship to a direct current component in said baseband signal. In a frequency modulation radio transceiver a broadcast function is provided by varying the low frequency signal with an information signal with the resulting local oscillator frequency being varied accordingly and amplified for broadcast. The transceiver is controlled to operate alternately in either a receive mode and a broadcast mode at substantially the same frequency. While in the receive mode the controlled oscillator causes the local oscillator signal to be drawn toward the carrier frequency of a received signal yielding preferred direct conversion of modulating information into the base band.

摘要： A mixer is designed to operate from a low voltage power source connected via a power terminal and ground and includes a balanced mixer circuit with a balanced input port for receiving local oscillator signals, and a pair of input terminals. A biasing circuit includes, an active voltage divider connected between the power terminal and ground to provide higher and lower voltages at first and second voltage taps. A differential driver circuit includes first and second transistors, collectors of which are each direct coupled to separate ones of the pair of input terminals. The first transistor has a base coupled via a capacitor to a single ended receive signal terminal, and an emitter coupled via a first resistor to ground. The second transistor has a base coupled via a capacitor to grounds, and an emitter coupled via a second resistor to the single ended receive signal terminal. The single ended receive signal terminal is also coupled with ground via an impedance element, in one example third resistor. A fourth resistor is connected between the first voltage tap and the base of the second transistor and, a fifth resistor is connected between the second voltage tap and the base electrode of the first transistor.
