25/06/03 - Adjusting OPAMP, Source voltage to TTL level
25/05/31 - Add external feedback circuit (General OPAMP supports weak output current)
Blue Line : Sine Wave
Green Line : Square Wave
Orange Line : Triangle Wave
Recommand OPAMP at 1MHz :
Sine wave GEN : LM318 or higher (SR ＞ 35V/us)
Square wave GEN : AD845 or use 7414, 7404
Triangle wave GEN : 7414, 7404 + LM318
Recommend Diode at 1MHz : 1N4147 or faster
(Changing LC Value = Changing Function Frequency)
