Fast analog sampler with great memory depth

摘要

An analog sampler (1) for recording analog data carried by a bus (5) comprises an array (10) of recording cells (2) arranged in rows (13) and columns (12). Each cell (2) has an analog input (3) coupled to the bus (5) by means of a switch (21a) having a controlling digital input (23). The device is characterized in that it comprises a delay line (9) associated with each column (12), coupled to the shift register. Successive outputs (11) of the line (9) are coupled to each of the digital inputs (11-1) of the cells (2) of the column (12) such that at any moment there is no more than one switch of a single recording switch. The signal is thus not disrupted by noise.
