專利摘要 |
A zero-crossing-based analog-to-digital converter having current mismatch correction capability, that can raise resolution, energy efficiency, and sampling rate of a fully differential zero-crossing circuit, is realized through a 90nm COMS technology. The circuit is used mainly to correct offset error, to use a current supply separation technology and a digital correction mechanism to correct mismatch among a plurality of current supplies. |
