Application No. 09/667,826
28. An additional column select switch 203 optionally may be provided
within readout cell 100 (col. 12, lines 32-34).
29. A row select switch 204 is also provided, which receives the row
select signal (RS) which is activated when readout of the specific row
corresponding to the readout cell 100 is desired (col. 12, lines 34-37).
30. When the appropriate column select and row select strobes are
presented, the constant current source 202 will be connected to the microbolometer
element 200 and the row select switch 204 will be closed so that a voltage appears
at node 206 corresponding to the voltage drop VD across the microbolometer
element (col. 12, lines 38-43).
31. A short time after the closing of the column select and row select
switches corresponding to the specific readout cell 100 are completed, sufficient to
give time for the detector sample voltage VD to stabilize, the control signal
SAMPLE is applied to sampling switch 208 (col. 12, lines 43-47).
32. The closure of switch 208 causes a voltage to appear at node 210
which, given sufficient time to settle, will correspond to the sampled value of the
microbolometer voltage VD (col. 12, lines 48-50).
