<abstract>This paper proposes a diode-free Operational Transresistance Amplifier (OTRA) based Time Marker Generator (TMG). It comprises of three stages. The first stage uses OTRA in open loop configuration, behaving as a comparator. A RC differentiator is used in the second stage to achieve voltage spikes. The third stage employs a MOS transistor to obtain the desired output. The proposed time marker generates spikes at positive or negative cross points depending upon the type of MOS transistor used. To illustrate the operation of the proposed TMG, SPICE simulations are performed using CMOS based OTRA implementation that uses 0.18 μm CMOS technology parameters. Simulations corroborate with the theoretical predictions.</abstract>
