Title: Light guide type modulator
Inventor: KIYONO MINORU
IPC: G02F1/035
Filed: 1988-03-11
Abstract: PURPOSE:To widen the modulation band of the modulator by a simple process by forming a space part near the outside of an electrode for signals along the longitudinal direction thereof. CONSTITUTION:An earth electrode 3b and the electrode 3a for signals are formed via a buffer layer 4 on a lithium niobate substrate 11 on which light guides 2 are formed. The space part 11a is provided near the outside of the electrode 3a for signals along the longitudinal direction thereof. An air layer of a small dielectric constant is, therefore, provided by this space and the effective refractive index of the microwaves propagating in the electrode 3a is lowered by as much as the space part 11a and is approximated to the refractive index of the light waves propagating in the light guides 2. As a result, the speed difference between the light waves and the microwaves is decreased and the modulation speed is increased. The modulation band is thus widened by using the simple production process.

IPC: H01L27/04
Filed: 1993-03-19
Abstract: PURPOSE:To secure of operable frequencies as a multichip module by series- connecting AC characteristic measuring circuit formed in an IC chip and by measuring signal delay time from an input terminal to an output terminal. CONSTITUTION:AC characteristics measurement is conducted by using a circuit whose input terminal is an external connection pad 6a to series-connect gate circuits 11-14 and whose output terminal is an external connection pad 6b. Signal delay time tpd from the pad 6a to the pad 6b is measured. This provides tpd=SIGMA (delay time of AC characteristics measuring gate circuits 11-14)+SIGMA (delay time of an internal wiring 8 used for AC characteristic measurement). That is, it follows that signal delay time tpd as the whole multichip module has been measured. In the relation between this signal delay time tpd and operable frequencies, in the case of securing an operable frequency of 50MHz, a signal delay time tpd of 7.5nsec or less can be selected.

Title: Switched capacitor filter
Inventor: KAWAKAMI IZUMI
IPC: H03H19/00
Filed: 1980-05-07
Abstract: PURPOSE:To prevent an increase of voltage for the output of each integrator, by using a capacitor having a constant transmission function of an equivalent leapfrog type active filter and decided with different resistance values for an LC simulation- type switched capacitor filter which is suited for an LSI formation. CONSTITUTION:A switched capacitor filter SCF2 is formed by replacing the resistance of an integrator in a leapfrog type active filter 1 which functions as an equivalent circuit in an LC filter circuit with a capacitor C and a switch SW. The 1st integrator consists of an operational amplifier AMP1, resistances R1-R3 plus a capacitor C1; the 2nd integrator consists of an operational amplifier AMP2, resistances R4 and R5 plus a capacitor C3; and the 3rd integrator consists of an operational amplifier AMP3, resistances R6 and R7 plus a capacitor C4 respectively. In such constitution, the condition under which the transmission function is constant between the input and output is obtained along with the value with which R1, R2 and R7 are 1 and R3-R6 are not 1. Thus an increase of voltage is prevented for the output of an integrator. Then an SCF is constituted with a switch having a capacitor value equivalent to the resistance plus a switch frequency.
