摘要： A sense amplifier (38) uses a current source (40) to pull-up a product line (14) during as low-to-high transition. After a desired voltage is reached on the product line (14), the current source is turned off by a delay feedback circuit (44). A hold-up circuit (42) holds the product line at the desired voltage until a high-to-low transition occurs.
