Abstract

In a double data rate (DDR) counter and counting method used in, for example, an analog-to-digital conversion in, for example, a CMOS image sensor and method, a first stage of the counter generates a least significant bit (LSB) of the value in the counter. The first stage includes a first clock input and is edge-triggered on one of the rising and falling edges of a signal applied at the first clock input. The counter includes at least one second stage for generating another bit of the value in the counter. The second stage includes a second clock input and is edge-triggered on the other of the rising and falling edges of a signal applied at the second clock input.
