FIGURE 10A. CIRCUIT
Top Trace: Output at junction of 2.7
and 51
resistors;
5V/Div., 500ms/Div.
Center Trace: External output of triangular function generator;
2V/Div., 500ms/Div.
Bottom Trace: Output of “Log” generator; 10V/Div., 500ms/Div.
FIGURE 10B. FIGURE FUNCTION GENERATOR SWEEPING
1V/Div., 1s/Div.
Three tone test signals, highest frequency
≥
0.5MHz. Note the slight
asymmetry at the three second/cycle signal. This asymmetry is due to
slightly different positive and negative integration from the CA3080A
and from the PC board and component leakages at the 100pA level.
