Abstract
Apparatus and method for discharging the body of a monitored SOI device through first and second discharge circuits. The second discharge circuit is selectively activated when the body potential of the monitored SOI device is at a level such that the body charge of the monitored SOI device cannot be discharged entirely through the first discharge circuit within normal operating cycle time allowances.
Claims5
A method of discharging a monitored SOI device with a charged body, the method comprising the steps of:
- (a) coupling a first discharge circuit to the monitored SOI device;
- (b) coupling a second discharge circuit to the monitored SOI device;
- (c) discharging the body of the monitored SOI device through the first discharge circuit to ground;
- (d) determining when the body charge of the monitored SOI device reaches a predetermined level;
- and
- (e) selectively activating the second discharge circuit to discharge the body of the monitored SOI device through the second discharge circuit to ground when the body charge of the monitored SOI device has reached the predetermined level.
