Ganapathy has been responsible for the development of important new algorithms in timing resynthesis, high-performance test generation, and fault simulation. In his new position with SVR, Ganapathy will be responsible for setting the company's direction and thrust into structured custom design while assisting the company to build relationships with other partners in the IC design industry. In addition, he will assist SVR to define next-generation IC design products for 0.25 m and 0.18 m process environments. The device, designated MS131, encodes and decodes user and servo data stored on the HDD platter. It is manufactured using a 0.5 all-CMOS linear process.
Adaptive circuitry is used extensively to maintain performance in the new read channel.
The device operates from a single 5V supply and handles user data rates from 25 to 165 Mbits per second. At full speed, the MS131 consumes less than 860mW of nominal operating power in read mode. Optimal partitioning between linear and digital functions enables the mixed-signal device to minimize power and bit error rate while maximizing flexibility and silicon utilization. The MS131's adaptive circuitry automatically compensates for non-linear aspects of MR head response. The circuitry also detects and compensates for thermal asperities that can result in data loss.
