One bit digital to analog converter with relaxed filtering requirements |
摘要 |
A digital to analog converter utilizes two discrete time processing stages, such as switched capacitor integrator circuits, operating at different sampling rates when converting the digital input signal to an analog signal. Use of two different sampling rates relaxes the requirements on antialias filters used in the continuous time processing.
