Abstract
Abstract Ever more precise time information is required to separate independent events at planned and proposed particle physics experiments. Typically, a combination of internal gain, very fast amplifiers and complex sampling circuitry are used to achieve this high time resolution, which usually come at the price of additional power consumption, layout area and complexity. In this contribution a novel circuit to improve the time resolution of a Depleted Monolithic Active Pixel Sensor (DMAPS) is presented. Its amplifier feedback is designed such that within its dynamic range the time walk of the trailing edge of the amplifier is compensated, making it the better estimate of the time of arrival (ToA). At moderate layout cost, this circuit allows reduce the power consumption of the analogue front end and enables a simple time walk correction which can be implemented on the ASIC.
