摘要
Hard disk drive preamplifier timers and methods to calibrate hard disk drive preamplifier timers are disclosed. A timer in a hard disk drive preamplifier comprises a first switch to selectively store charge in a storage device based on an input signal, the storage device receiving a first current and storing the charge to cause the storage device to have a first voltage that increases at a first rate; a compensation device to cause the first voltage to be substantially equal to a second voltage after a predetermined time period; and a trigger to output a signal when the first voltage is substantially equal to the second voltage, the predetermined time period controlling a transition time between a first hard disk drive operating condition and a second hard disk drive operating condition different than the first operating condition.
