A technique to implement true-sample-and-hold circuits that hold the output for almost the entire clock cycle without resetting to zero is introduced, alleviating the slew rate requirement on the op-amp. It is based on a Miller op-amp with an auxilia

Publikováno v: I2MTC

Compressed sensing is a recently proposed technique aiming to acquire a signal with sparse or compressible representation in some domain, using a number of samples under the limit established by the Nyquist theorem. The challenge is to recover the se
