GW Detector Circuits (#130-A, ICL 7621 Circuit)

(11-20-91)


 


GW Detector Circuit # 130-A:

ICL 7621 Circuit:

Test System:

* Rin: to be chosen for best response ( ~ 1 to 2 k ohm)

Notes:

1. This is the set-up to be used for preliminary tests.
2. Rin on Buffer was made 470 k, for gain ~ 2x plus.
3. L.P. filter is 2-stage.
4. 15,000 uF Cin on GW detector is external (use jack).
5. Buffer stage (741) needed to drive Rustrak low-Z without instabilities.
