Abstract :
The recently introduced switched-MOSFET (SM) technique is a sampled-data technique suitable for low supply voltage operation since it avoids the conduction gap of the switches and does not need any dedicated process. Nevertheless, a formalization that allows one to establish the limits of the technique has not been presented yet. In this work, a detailed analysis of the basic SM delay cell is developed. The analysis includes offset correction, settling time, noise, charge injection and harmonic distortion
