1 Harrison, Reid R.; Myers, Chris J.; Schlegel, ChristianCell library for automatic synthesis of analog error control decodersThis paper presents a cell library for automatic synthesis of analog error control decoders. By using some basic cells, analog ermr control decoders can be automatically synthesized. Also, using automatic synthesis based on this cell library, the circuit performance is not degraded and the circuit i...2002
2 Harrison, Reid R.CMOS imager with on-chip temporal filtering for motion pre-processingRobust motion detection algorithms such as the motion energy model require temporal filtering at the pixel level. We have designed and tested a CMOS imager with integrated, pixel-level temporal filtering necessary for motion detection. This temporal filtering enhances transients and provides a ...2002-01-01
3 Harrison, Reid R.Floating gate current mirror for gain correction in CMOS translinear circuitsThe exponential behavior of MOSFETs in subthreshold operation has recently been exploited to build CMOS translinear circuits such as multipliers and log-domain filters. A major obstacle in developing a practical CMOS implementation is the variation in threshold voltage between devices. In transline...1999-01-01
4 Harrison, Reid R.Low-power, low-noise CMOS amplifier for neural recording applicationsThere is a need among scientists and clinicians for lownoise, low-power biosignal amplifiers capable of amplifying signals in the mHz to kHz range while rejecting large dc offsets generated at the electrode-tissue interface. The advent of fully-implantable multielectrode arrays has created the nee...2002-01-01
5 Harrison, Reid R.Power minimization of a 433-MHz LC VCO for an implantable neural recording systemThis paper presents a new random-search based integrated inductor optimization algorithm. The algorithm provides the designer with valuable information about design tradeoffs. it is used to design an inductor to minimize power dissopation in an LC VCO. The measured results show that a 53:1 power sav...2006
6 Harrison, Reid R.Power, clock, and data recovery in a wireless neural recording deviceFor many medical applications, neural recording systems should be fully implantable. Transcutaneous wires must be compleley eliminated, and this necessitates the wireless transfer of power, clock and configuration data to the device. We have developed, fabricated, and tested cirucits that recover po...2006
7 Harrison, Reid R.Signal amplification, detection and transmission in a wireless 100-electrode neural recording systemWe are developing a fully-implantable neural recording system with wireless power and data transfer. As part of this system, we have developed a low-power integrated circuit that performs power rectification and and regulation, reception of configuration data, neural signal amplification and filt...2006
8 Harrison, Reid R.Wide-linear-range subthreshold CMOS transconductor employing the back-gate effectWe present a CMOS circuit that utilizes the back-gate effect to extend the linear range of a subthreshold MOS transconductor. Previous designs of wide-linear-range transconductors using bipolar transistors employed multiple differential pairs with input offset voltages used to shift the individ...2002-01-01
