(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Eletrônica, 2013-05-10)
The industrial outsourced printed circuit boards production are economically viable for expressive ordering quantities. In the stage of boards layout development and validation, in which few amounts are produced, alternative ...
An accurate low-voltage analog memory-cell with built-in multiplication
(2001-01-01)
A CMOS memory-cell for dynamic storage of analog data and suitable for LVLP applications is proposed. Information is memorized as the gate-voltage of input-transistor of a gain-boosting triode-transconductor. The enhanced ...
