Abstract:
A continuous time filter of a read/write channel for a hard disk drive, wherein the continuous time filter is adapted to receive an analog signal, the continuous time filter comprising:a read filter circuit which filters the analog signal when the continuous time filter is in read mode and generates a read filter output signal; a servo filter circuit which filters the analog signal when the continuous time filter is in servo mode and generates a servo filter output signal; an input multiplexer, wherein the input multiplexer receives the analog signal and transmits the analog signal to the read filter circuit when the continuous time filter is in read mode and to the servo filter circuit when the continuous time filter is in servo mode; and an output multiplexer, wherein the output multiplexer receives and transmits the read filter output signal when the continuous time filter is in read mode and receives and transmits the servo filter output signal when the continuous time filter is in servo mode.
