In modern millimeter and sub-millimeter communication systems, particle physics, neutrino astronomy, and for passive applications in radio astronomy or remote atmospheric sensing, the trend is to eliminate analog functional blocks, such as mixers and filters, by converting the signal into the digital domain as early as possible in the processing chain. Therefore, fast analog-to-digital converters...
A track-and-hold (T&H) circuit has been designed and fabricated using the 65nm CMOS technology from STMicroelectronics. A fully differential architecture has been adopted. The circuit exhibits a −3dB input bandwidth wider than 8GHz. At 8GHz, the maximum sampling frequency, the measured overall power consumption and gain are 178mW and 0dB, respectively. The T&H core dissipates around 40mW....
