Abstract :
Track-and-hold amplifiers (THA) are key components for high-speed and medium-resolution A/D-converters for measurement, multimedia, and advanced digital signal processing systems. This THA architecture provides a substantial improvement in linearity. The THA chip incorporates only npn transistors and is fabricated in a 25GHz-f/sub T/ silicon bipolar production technology with an effective emitter stripe width of 0.4/spl mu/m. It offers 10b linearity over the full Nyquist band at 1GSample/s. Compared to the 8b 1GSample/s circuit that is the starting point for the development of the current IC, the THD is improved by more than 10dB while keeping the power dissipation at a similar level (490mW).
