【 摘 要 】

References(10)This paper presents a new area-efficient and fast sampling multiplexer for battery monitor system. This multiplexer structure introduces a full differential leapfrog sampling scheme which leads to half of occupied area, less sampling time and higher common mode rejection rate (CMRR) than the traditional one. This kind of multiplexer structure was introduced in a 12-ch battery monitor IC which fabricated with 60 V BCD process. The measurement result shows that the presented multiplexer achieves a channel mismatch error up to 1.2 mV (Typical) while the battery monitor IC works in 400 ns sampling time.
