Density evolution analysis of device mismatch in analog decoders
Chris Winstead, Christian B. Schlegel · 2004
All analog circuits are affected by device mismatch, slight errors in the physical characteristics of analog devices. In many applications, mismatch reduces precision, making power and complexity advantages irrelevant. In this paper, we examine the effects of mismatch for decoders based on Gilbert multipliers and the sum-product algorithm.
