Abstract :
This paper present an analytical model of delay for subthreshold voltage to time converters (VTCs). The model characterizes an equation between the input voltage and output delay. Delay prediction model can be used to compute delay and understand characteristic of VTC in subthreshold region. Simulations are done in 0.18um CMOS technology and results ensure the accuracy of the model.
