Abstract :
This paper describes a high-precision Movable Parts Manager (MPM) for BD/DVD applications. To realize the high precise optical pick-up control, the MPM employs a mixed-signal actuator driver (MiSiA) with direct voltage feedback method using simple 1st-order delta-sigma ADCs. It achieves high resolution of 1% linearity error and 0.2% DC error. The chip size of the MPM is 7.6mm2 in 65nm CMOS processes. The MPM can be applied to next-generation high-density recording systems.
