士模SAR ADC产品CM2248、CM2268和CM2368采用士模原创的变增益放大器直驱SAR ADC内核架构(直驱direct-drive架构),实现了较国际竞品更高的信噪比和更低的功耗,并通过正向设计突破工艺瓶颈,实现了境内流片,更大限度地保障了供应安全。 逐次逼近型(SAR)ADC由于其极佳 ...
在繁多的需求之下,目前的大多数SAR和Sigma-Delta (DS) ADC都将惨遭淘汰,因为在满足频率和延迟需求的同时还要实现低成本和低功耗目标太难。本文将介绍一种差分、面积有效型16位自校准SAR ADC的设计。 对于之前使用分立ADC的应用,包括电能计量、手持式医疗设备 ...
Generally, you will find the SAR (successive-approximation-register) and delta-sigma (??) analog-to-digital converters (ADCs) in lower frequency applications. The signal chain for these applications ...
What do the circuits look like for 12-bit, analog-to-digital converter (ADC) systems? These systems can be found in handheld meters, data loggers, automotive systems, and monitoring systems, to name a ...
