Staircase Generator
Figure 10 shows a staircase generator circuit utilizing three
CMOS operational amplifiers. Two CA3130s are used; one
as a multivibrator, the other as a hysteresis switch. The third
amplifier, a CA3160, is used as a linear staircase generator.
Picoammeter Circuit
Figure 11 is a current-to-voltage converter configuration
utilizing a CA3160 and CA3140 to provide a picoampere
meter for 13pA full scale meter deflection. By placing
Terminals 2 and 4 of the CA3160 at ground potential, the
CA3160 input is operated in the “guarded mode”. Under this
operating condition, even slight leakage resistance present
between Terminals 3 and 2 or between Terminals 3 and 4
would result in zero voltage across this leakage resistance,
thus substantially reducing the leakage current.
If the CA3160 is operated with the same voltage on input
Terminals 3 and 2 as on Terminal 4, a further reduction in the
