Abstract
Disclosed is a sample-and-hold unit more especially designed to work at microwave frequencies (>1 GHz). In order to increase the sampling frequency, the disclosed circuit has at least two identical parallel channels. Each channel has a first follower switch (9) a capacitor (11) and a second holding switch (15). The channels are controlled by a single clock, the complementary or phase-shifted signals (H, H) of which address the samples sequentially towards the output (8). The disclosed device can be applied to the processing of analog signals.
