  • Patent number: 11558064
    Abstract: SAR ADC and sampling method based on single-channel TIS. The SAR ADC comprises: a capacitor array comprising a weight capacitor and a compensation capacitor, a first switch array, a second switch array, a channel switch group and a sampling switch; when in a sampling state: a lower plate of the weight capacitor is connected to an input voltage by means of the first switch array, and an upper plate of the capacitor array is connected to a common mode voltage by the sampling switch and the channel switch group; when in a successive approximation state: the lower plate of the weight capacitor is connected to a reference voltage by the second switch array. Input signals are sampled by using a unified to sampling switch, which solves the problem in the traditional technology that sampling moments are mismatched due to different sampling signals in each time-interleaved channel.

  • Patent number: 10997464
    Abstract: Digital image layout training is described using wireframe rendering within a generative adversarial network (GAN) system. A GAN system is employed to train the generator module to refine digital image layouts. To do so, a wireframe rendering discriminator module rasterizes a refined digital training digital image layout received from a generator module into a wireframe digital image layout. The wireframe digital image layout is then compared with at least one ground truth digital image layout using a loss function as part of machine learning by the wireframe discriminator module. The generator module is then trained by backpropagating a result of the comparison.
