Time encoding is a mechanism for representing the information contained in a continuous time, bandlimited, analog signal
as the zero-crossings of a binary signal. Time decoding algorithms
have been developed that make a perfect recovery of time encoded
bandlimited signals possible. We consider a simple one-opamp active
RC implementation of the time encoder and investigate the robustness
in performance of the time decoder when the former is subject to
non-idealities of the analog VLSI realization. We show that up to a
constant scaling factor, delay and offset the input signal can be accurately
reconstructed even if the opamp has a finite DC gain and finite bandwidth
and the circuit exhibits parameter offsets. We develop an experimental
upper bound for the reconstruction error that can be used in the
design of the encoder. The analytical results are verified with numerical
simulations.
