Abstract
A counter can have a number of sensing components. Each respective sensing component can be configured to sense a respective event and can include a respective first capacitor configured to be selectively coupled to a second capacitor in response to the respective sensing component sensing the respective event. The second capacitor can be configured to be charged to a voltage by each respective first capacitor that is selectively coupled to the second capacitor. The counter can have a comparator with a first input coupled to the second capacitor and a second input coupled to a reference voltage corresponding to a threshold quantity of events. The comparator can be configured to output a signal indicative of the threshold quantity of events being sensed in response to the voltage of the second capacitor being greater than or equal to the reference voltage.
