摘要： PURPOSE:To change the time constant of charge/discharge and to facilitate easy conversion of a rectification detecting circuit into an LSI, by providing an LPF of a switched capacitor film to the smooth part of the rectification detecting circuit and controlling the frequencies before and after detection of rectification for the clock pulse of said LPF. CONSTITUTION:A rectification detecting circuit rectifies an AC signal and converts it into a direct current by means of operational amplifiers 2 and 5. An LPF12 of a switched capacitor filter is provided to the smooth part of the rectification detecting circuit. At the same time, a logical circuit is provided to said detecting circuit to give a logical operation to the clock inputs given from clock input terminals 9 and 10. The clocks phi and -phi given from said logical circuit are applied to MOS transistors Tr1-Tr6 of the LPF12. Then the time during which an AC signal is supplied to the rectification detecting circuit and then detected is set freely together with the time during which the AC signal is cut off and the rectification detecting circuit is recovered. Based on these set times, the frequency of the LPF12 is controlled before and after a rectification detecting mode. Then the time constant of charge/discharge is varied to convert the rectification detecting circuit into an LSI.

摘要： PROBLEM TO BE SOLVED: To improve an output side reflection characteristic in a high frequency band by dividing the connection areas of DC level shift diodes by an optional integer and arranging the divided diodes in a distribution type. SOLUTION: A DC level shift circuit that is configured by using a drain ground transistor 3 and the optional number of DC level shift diodes 29 that are serially connected is used as a unit circuit. The connection part areas of the diodes 29 are divided by an optional integer and the divided diodes 29 are arranged in a distribution type. Thus, an output side reflection characteristic in a high frequency band is improved. Also, the speed mismatching between input-output pseudo-regular K type filter circuits which occurs by division is improved by inserting a transmission line or an inductance 31 between anode terminals of the divided diodes 29 that are the closest to the transistor 3.

摘要： PURPOSE:To prevent the provision of the peak detecting function from degrading the high frequency performance by dividing the output of a clamping circuit into an output for high-speed data signal and a signal output for peak detection by a differential circuit. CONSTITUTION:The output of the clamping circuit consisting of C1, D1, R1, and R2 is connected to one input terminal Ia1 of a differential circuit A, and the other input terminal Ia2 is DC-biased by a bias circuit B. One output terminal Oa1 of the differential circuit A is used as the main signal output terminal from which a high-speed data signal is sent to the next stage, The other output terminal 0a2 is connected to the input of the peak detecting circuit consisting of D2, C2, and R3. Since an input signal is divided into a main signal and an auxiliary signal for peak detection by the differential circuit A and the capacity component of the diode D2 for peak detection does not exist in the route of the high-speed main signal, the circuit is operated at a high speed.

摘要： PURPOSE:To attenuate a high frequency component leaked to the circuit and to improve the broad band characteristic by connecting one terminal of a 3rd transmission circuit with respect to a transmission line to the ground through an adjacent transmission line and a 3rd termination circuit comprising series connection of a resistive element and a capacitive element in this order.

摘要： PURPOSE:To reduce the DC and high-frequency impedance between bonding pads and a mount by a method wherein the mount is made higher by providing a step, and the pellet is surrounded with a conductive ring of the same potential as that of the mount; then, pellet is bonded to the conductive ring. CONSTITUTION:A conductive ring pattern 61 is connected to the mount 13 at a low impedance in a DC and high-frequency manner with a four-sided side-surface metallize. Bonding pads 14, 15 to be set at the same potential as that of the mount 13 is DC and high-frequency manner are bonded to this conductive ring pattern 61. Further, this pattern is bonded to case leads 62, 63. This manner enables extreme reduction in the Dc and high-frequency impedance between the bonding pad 14 or 15 and the mount 13. Besides, the workability and the reliability can be improved without contamination of the bonding surface of the conductive ring pattern 61 with solder because this surface is made higher by providing a stepwise difference from the mount 13.

摘要： PURPOSE:To make a setting time adjustment unnecessary and reduce a capacity value, by obtaining a timer setting time of a timer circuit with a capacity ratio and a switching period in the constitution in which electric charge is redistributed by a capacity and switches. CONSTITUTION:A switch 13 is turned on and a capacity 11 is charged with an power source 5. Switches 12, 13 are turned off and a switch 14 turned on, and an electric charge of the capacity 11 is redistributed to a capacity 10. The switch 14 is turned off and the switch 13 turned on, the capacity 11 is charged again with the source 5. The switch 13 is turned off and the switch 14 on, an electric charge of the capacity 11 is redistributed to the capacity 10. These operations are repeated and when a minus input terminal 2 of a differential amplifier 1 exceeds a reference voltage VR, an output of the amplifier 1 is inverted. A timer setting time is decided by a capacity ratio of the capacity 10 to the switching periods of the switches 13, 14 and the capacity 11.
