  • Method of detecting the frequency of an input clock signal of an integrated circuit and integrated circuit
    Patent number: 7737730
    Abstract: An integrated circuit includes a first switched capacitor element and a second switched capacitor element, which are coupled to form a bridge circuit, the first switched capacitor element being located in a first branch of the bridge circuit and the second switched capacitor element being located in a second branch of the bridge circuit. A detector circuit is coupled to the first branch and to the second branch of the bridge circuit. Switching signals of the first switched capacitor element and of the second switched capacitor element are generated on the basis of an input clock signal of the integrated circuit.

  • Electronic circuit and manufacturing method for electronic circuit
    Patent number: 6181190
    Abstract: The conductance may be adjusted of an electronic circuit including a first electronic component having a nominal conductance with a given inaccuracy. The circuit includes at least one additional field effect transistor connected in parallel with the component. The sources of all field effect transistors are connected to a common source, the drains of all field effect transistors are connected to a common drain, and a control unit controls the gate voltage of each field effect transistor individually. The gate voltage is controlled by connecting the gate voltage of each field effect transistor either to a common gate or to the common source. The component may be used to form switches or amplifiers or to control the conductance of circuits including other electronic components serially connected with the electronic circuit.
