High-speed high-precision voltage-mode MIN/MAX circuits in CMOS technology

A new circuit for multiple-input voltage-mode min/max circuits that, unlike conventional implementations, do not have large voltage swings at any of the internal nodes, is discussed. This scheme is characterized by high-speed, high-precision and simple architecture. The proposed circuit exhibits linear complexity with the number of inputs. A test chip prototype with a three-input max circuit has been designed and built in a 0.8 /spl mu/m CMOS technology and experimental results are shown that verify the proposed approach.
