Abstract

Spike based imagers commonly use either time-to-first spike (TTFS) or spike rate encoding exclusively. In this paper we discuss the benefits of using a mixed-mode encoding scheme backed by theoretical analysis and SPICE simulations. The mixed-mode readout uses both TTFS and spike rate information to estimate the illumination for each pixel, which lessens the maximum spike rate and timing clock speeds required for a given level of accuracy. We intend to test this methodology on a generic spike based imager chip we have designed and submitted for fabrication in a 0.13μm 3D SOI CMOS process. The imager is capable of both TTFS and spike rate encoding and should allow us to fully validate our theory.
使用混合模式编码读出的基于尖峰的3D成像芯片
基于尖峰的成像仪通常只使用第一个尖峰时间(TTFS)或尖峰率编码。在本文中,我们讨论了使用混合模式编码方案的好处,支持理论分析和SPICE模拟。混合模式读出使用TTFS和尖峰率信息来估计每个像素的照明,这降低了给定精度级别所需的最大尖峰率和定时时钟速度。我们打算在我们设计并提交的用于0.13μm 3D SOI CMOS工艺制造的通用脉冲成像芯片上测试该方法。成像仪能够TTFS和峰值速率编码,应该允许我们完全验证我们的理论。
