The key challenges in designing a multi-channel biosignal acquisition system for an ambulatory or invasive medical application with a high channel count are reducing the power consumption, area consumption and the outgoing wire count. This article proposes a spread-spectrum modulated biosignal acquisition system using a shared amplifier and...

Low-voltage and low-power front-end design is required for the safe and long-term monitoring of cardiac signals. To address the low-voltage challenge, this paper presents a subthreshold source-coupled logic (STSCL) based time-domain comparator designed in 180 nm CMOS process technology. At a low supply voltage of 0.8 V, the STSCL time-domain...

This paper presents a novel multichannel level-crossing (MLC) ADC architecture aimed at recording atrial electrograms from multiple channels. The proposed architecture combines synchronous sampling with level-crossing (LC) quantisation to achieve activity dependent operation while recording from multiple channels simultaneously. In the...
