ABSTRACT:
A high input impedance circuit is employed to sense the condition of a bridge such as a Wheatstone bridge containing ionization chambers for smoke detection. The circuit comprises two CMOS inverters connected to operate as a differential signal detector, one inverter connected at its gate electrodes to one output terminal of the bridge and the other similarly connected to the other output terminal of the bridge. The system includes a simple null and sensitivity adjustment.
