摘要

设计了一个3 /spl mu/V的偏置运算放大器，同时使用自动调零和斩波，在直流下提供20 nV//spl径向/Hz的输入噪声，在斩波频率下具有低能量。该设计包括用于减少开关瞬变的附加电路。功率消耗是4mw从5v电源。采用0.6/spl mu/m双聚双金属CMOS工艺，模具面积为0.6/spl倍/1.12 mm。

A 3 /spl mu/V-offset operational amplifier with 20 nV//spl radic/Hz input noise PSD at DC employing both chopping and autozeroing

A 3 /spl mu/V offset op-amp has been designed using both autozeroing and chopping to give 20 nV//spl radic/Hz input noise at DC with low energy at the chopping frequency. The design includes additional circuitry for reduced switching transients. Power consumption is 4 mW from a 5 V supply. Die area is 0.6/spl times/1.12 mm using a 0.6 /spl mu/m double-poly double-metal CMOS process.
