Yes, this is a simple curved log cabin block.
The larger the difference between the narrow side of the block's strips and the wider side of the block's strips, the more pronounced the curve will be.
I recently did one the created an almost perfect circle when the curves were placed together. I cut my strips at 1 & 5/8 for the wider side, and 1 & 1/4 for the narrow side. Here is the graph for the blocks.
