Abstract :
This paper describes the design and realization of a buffered track and hold (BTH) circuit fabricated in InP-InGaAs-InP double heterojunction bipolar transistor (DHBT) technology (FT = 180 GHz). This BTH is intended for a single shot, 20 GHz bandwidth and 40 GS/s sampling frequency digitizer based on the non simultaneous spatial sampling principle. Based on a high speed switched emitter follower (SEF), the BTH can ensure 20 GHz bandwidth signal compatible with the targeted objectives. First experimental results in the frequency domain and a novel optimized architecture leading to a combination between the SEF and the Cherry Hooper design based buffer are also presented.
