Title:
CONVERTED VOLTAGE-GENERATING DEVICE
Document Type and Number:
Japanese Patent JP3888697
Kind Code:
B2
Abstract:
PURPOSE: To generate a temperature-compensated trapezoidal wave of vertical frequency.
CONSTITUTION: In the starting 1/3 of a TRACE period, a signal V102 is lower than 5.6 V, a diode CR20 turns on, and a transistor Q01 turns off, forming a TR1 part. When the signal V102 exceeds 5.6 V, the diode CR20 turns off and the transistor 01 holds a trapezoidal signal VT at CLAMP level for 1/3 of the TRACE period, thereby forming a TR2 part. Then the diode CR2 turns on in the ending 1/3 of the TRACE period, the diode CR21 turns on and the transistor Q01 turns off, forming a TR3 part.
