High-speed Sampling System in CMOS

In this paper we will present a high-speed sampling system intended for use in a depth selective or depth resolved spectroscopic LIDAR for transcutanuous blood assessment. A continuous-time (CT) sampling solution enabling sampling rates close to 100 GHz, close to two orders of magnitude faster than standard clocked systems. Based on experimental verification in 90nm CMOS technology, opportunities and limitations of CT sampling systems are analyzed.
