The heart of the frequency-determining system is an

the threshold detector is fed back via resistor R

Operation with Output-Stage Power-Booster
The current-sourcing and-sinking capability of the CA3130
output stage is easily supplemented to provide power-boost
capability. In the circuit of Figure 17, three CMOS transistor-
pairs in a single CA3600E (see Note 12) lC array are shown
parallel connected with the output stage in the CA3130. In the
Class A mode of CA3600E shown, a typical device consumes
20mA of supply current at 15V operation. This arrangement
boosts the current-handling capability of the CA3130 output
stage by about 2.5X.
