Optical single-clock-pulse generator using a photoconductive sample-and-Hold Circuit for processing ultrafast asynchronous optical packets
IEEE Photonics Technology Letters, 2002Co-Authors: Tatsushi Nakahara, Hiromichi Takenouchi, Ryo Takahashi, Hiroyuki SuzukiAbstract:A scheme is proposed for generating a packet-level optical single-clock-pulse that uses an InP metal-semiconductor-metal photodiode-based sample-and-Hold Circuit and a gain-switched laser diode. A 3.3-ps single-pulse generation synchronized to the first bit pulse of an incoming ultrafast burst optical packet is demonstrated. The generated pulse has constant timing, intensity, and polarization; hence, it is suitable for use as the control pulse of an all-optical switching device used in a photonic packet-switched network node operating at over 40 Gbit/s

High-speed high-precision optically controlled sample and Hold Circuit for analog to digital conversion
International Conference on Optical Information Processing, 1994Co-Authors: Chen Kuo Sun, Ching Ten Chang, William H. McknightAbstract:A novel bridge type opto-electronic (OE) sample and Hold Circuit based upon current steering is presented and experimentally tested. Comparison between this Circuit and a more conventional or direct OE sample and Hold Circuit which draws charge directly from the signal source shows that the bridge type is clearly superior in performance to the direct OE Circuit. When a high speed signal is to be sampled with considerable precision, the bridge type OE sample and Hold Circuit offers high charging capability, much needed signal isolation, and reduced time jitter, distinct advantages over electronic sample and Hold Circuits.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

Bridge-type optoelectronic sample and Hold Circuit
Optical Technology for Microwave Applications V, 1991Co-Authors: Chen Kuo Sun, Ching Ten Chang, William H. McknightAbstract:A novel bridge type optoelectric (OE) sample and Hold Circuit based upon current steering is proposed for the first time and is experimentally tested. Experimental comparison between this Circuit and the conventional direct OE sample and Hold Circuit shows that the bridge type is clearly superior in performance to the direct OE Circuit. When a high speed signal is sampled with high accuracy, the bridge type OE sample and Hold Circuit offers high charging capability, commanding signal isolation, and reduced time jitter, distinct advantages over electronic sample and Hold Circuits.

A bridge type optoelectronic sample and Hold Circuit
Journal of Lightwave Technology, 1991Co-Authors: Chen Kuo Sun, Ching Ten Chang, William H. McknightAbstract:A novel bridge-type optoelectronic (OE) sample-and-Hold Circuit based on current steering is proposed and experimentally tested. Experimental comparison between this Circuit and the conventional direct OE sample-and-Hold Circuit shows that the bridge type is clearly superior in performance to the direct OE Circuit. When a high speed signal is sampled with high accuracy, the bridge-type OE sample-and-Hold is potentially more advantageous over the conventional electronic sample and Hold in terms of large charging current capability, commanding signal isolation, fabrication simplicity, accurate timing control, and less time jitter. >

Wide-range single-ended CMOS track-and-Hold Circuit
IEICE Electronics Express, 2007Co-Authors: H. Movahedian, Behnam Sedighi, Mehrdad Sharif BakhtiarAbstract:This paper investigates the performance of a MOS track-and-Hold Circuit as the front end of a wide input range and high-speed single-sided ADC. In order to reduce charge injection and clock feedthrough errors, a new technique for employing a dummy transistor in the bootstrapped switch of the track and Hold Circuit is introduced. Performance of the proposed Circuit for the two cases of constant and non-linear Hold capacitor is studied. It is also shown that how and when dummy switch and bulk switching method can improve the accuracy of the T/H.
