    摘要： The mixer amplifier includes an amplification stage having a current source circuit and a plug filter adapted to modify the current circulating in the current source circuit. The amplification stage and a mixer stage amplify an incoming signal and transpose the frequency of the signal to a predetermined frequency. Resistors pairs measure the imbalance between two branches and have a relatively high value (thus creating a high-pass filter). When the branches are perfectly balanced, the voltage tapped by the non-inverting terminal of the operational amplifier A is zero. During an imbalance, this voltage rises. The output of the amplifier drives the TNP transistor T9, causing current to flow into branches to solicit the transistors T7 or T8 of the current source circuits and thus return the two branches to balance. Accordingly, a balance is maintained between the two branches by providing a feedback within the mixer amplifier.

    摘要： An integrated electronic circuit comprises at least first and second variable resonator elements that can be tuned by means of an electric signal (Vtune) and that are arranged on the same silicon substrate, and that are respectively integrated into a Master circuit and a Slave circuit. Each resonator element is associated with a first inductive partner element set in the vicinity of the resonant and antiresonant frequencies; and with a second capacitive partner element, at least one of said partner elements being adjustable by means of said electric signal (Vtune). Controlling both partner elements could be done either by means of an adjustable capacitor, as a varactor, or by means of an inductor, passive or active, fixed or variable.

    摘要： A heterodyne receiving circuit for a digital communication system including a first band pass filter receiving a signal from an antenna, an amplifying circuit and a second narrow band pass filter for selecting one particular channel within a band of frequencies. The two filters are carried out with integrated BAW-type tunable resonators which can be adjusted, respectively, by a first electrical signal and a second electrical signal generated by two PLL-type frequency control loops. The second frequency control loop has a variable division factor for the purpose of selecting one particular channel within said band of frequencies. In addition, the receiving circuit includes a mixer for mixing the signal generated at the output of said second filter with a local oscillation frequency in order to produce an intermediate frequency. The division factor is controlled by a digital processing of the intermediate frequency.
