Latest Patents

Lei Mei holds a patent for a "Data delay cell for rise time programming in write preamplifier." This innovative data delay circuit is designed to delay a portion of a data signal for application to a write head of a hard disk drive. The circuit includes a data delay cell that comprises two inverters and a charge current source for charging at least one of the inverters. Additionally, it features a bias circuit that programs the delay of the data delay cell. The bias circuit operates in a current-mirroring relationship with the charge current source and incorporates a current-based digital-to-analog converter (DAC) for programmably selecting the delay. To address gain error, the data delay circuit includes compensation circuitry, which may consist of replica charge current and reference current sources that are fed back through a gain cell.
