Harrison, Reid R. | Analog MAP decoder for (8,4) hamming code in subthreshold CMOS | An all-MOS analog tail-biting MAP decoder is presented for an (8,4) Hamming code. The decoder implements a probability propagation algorithm using subthreshold CMOS networks. Physical results verify the expected behavior of the decoder and demonstrate robustness of analog decoding circuits. | MAP decoder; Hamming code; VLSI | 2004-01-01 |

Harrison, Reid R. | Biologically inspired analog IC for visual collision detection | We have designed and tested a single-chip analog VLSI sensor that detects imminent collisions by measuring radially expanding optic flow. The design of the chip is based on a model proposed to explain leg-extension behavior in flies during landing approaches. We evaluated a detailed version of thi... | Visual collision detection; VLSI | 2005-11 |

Harrison, Reid R. | CMOS programmable analog memory-cell array using floating-gate circuits | The complexity of analog VLSI systems is often limited by the number of pins on a chip rather than by the die area. Currently, many analog parameters and biases are stored off-chip. Moving parameter storage on-chip could save pins and allow us to create complex programmable analog systems. In this ... | Computer chips; VLSI; Computer memory; Potentiometers; CMOS circuits; Floating gate circuit | 2001-01 |

Harrison, Reid R. | Local field potential measurement with low-power analog integrated circuit | Local field potentials (LFPs) in the brain are an important source of information for basic research and clinical (i.e., neuroprosthetic) applications. The energy contained in certain bands of LFPs in the 10-100 Hz range has been shown to correlate with specific arm movement parameters in nonhuman ... | Local field potentials; Neural recording; Low-power circuit design; Neural prosthesis; VLSI | 2004-01-01 |

Harrison, Reid R. | Validation of adaptive threshold spike detector for neural recording | We compare the performance of algorithms for automatic spike detection in neural recording applications. Each algorithm sets a threshold based on an estimate of the background noise level. The adaptive spike detection algorithm is suitable for implementation in analog VLSI; results from a proof-of-... | Spike detection; Neural recording; Ation potential; VLSI | 2004-01-01 |
