Title: Variable phase shifting circuit
Inventor: HAYAKAWA MITCHRU
IPC: H03H11/20
Filed: 1987-05-25
Granted: 1990-07-05
Abstract: The input signal (vi) to a voltage controlled phase shifter is applied to a phase splitter (4). This generates two signals (V1, V2) with a relative phase difference of 90 degress. These signals are fed as respective inputs to two double balanced differential amplifiers (5,6), the outputs from which are summed (7) to provide the phase shifted output (V0). A phase control voltage (Vx) is converted (8) to a current (Ix) which is passed to a voltage (AV1) for controlling the differential amplifier (5) and to circular function (10) and logarithmic (11) connecters in succession to generate a voltage (AV2) for controlling the second differential amplifier (6).

Abstract: PURPOSE: A method for driving a solid state image sensor is provided to improve a dynamic range by raising periodically a voltage applied to a substrate and removing an over-input light. CONSTITUTION: A high pulse is applied to a transfer gate. The second voltage higher than the first voltage applied to a substrate is applied to the substrate before a moving point t1 of a signal charge collected in an n-type photo diode. The over-charge is discharged outside the substrate. Accordingly, the charge of Q0 remains on a region of the photo diode. The voltage of the substrate returns to an initial state and the photo diode receives input light corresponding to the time t1.
