Function Generator
A function generator having a wide tuning range is shown in
Figure 12. The adjustment range, in excess of 1,000,000/1,
is accomplished by a single potentiometer. Three operational
amplifiers are utilized: a CA5160 as a voltage follower, a
CA3080 as a high-speed comparator, and a second
CA3080A as a programmable current source. Three variable
capacitors C1, C2, and C3 shape the triangular signal
between 500kHz and 1MHz. Capacitors C4, C5, and the
trimmer potentiometer in series with C5 maintain essentially
constant (±10%) amplitude up to 1MHz.
Staircase Generator
Figure 13 shows a staircase generator circuit utilizing three
CMOS operational amplifiers. Two CA5130s are used; one as a
multivibrator, the other as a hysteresis switch. The third amplifier,
a CA5160, is used as a linear staircase generator.
