Abstract
A dynamic analog content addressable memory (CAM) cell uses volatile memory to store a range. The dynamic analog CAM cell includes an upper bound circuit and a lower bound circuit. The upper bound circuit includes a first pull-down transistor and a first controlled current generator. The first controlled current generator is configured to store an upper bound of the range in a first dynamic memory circuit, and to activate the first pull-down transistor when an analog input value is greater than the upper bound of the range. The lower bound circuit includes a second pull-down transistor and a second controlled current generator. The second controlled current generator is configured to store a lower bound of the range in a second dynamic memory circuit, and to activate the second pull-down transistor when the analog input value is less than the lower bound of the range.
