This paper describes the design of a CMOS analog discrete-time equalizer for perpendicular magnetic recording (PMR) read channel. In this design the structure of analog FIR filter that places rotating switch matrix between DAC and multiplier has been proposed. It reduces an accumulative switching error in analog samples due to rotating switch matrix. A 7-tap filter circuit based on GPR2 target was...
This paper presents a design of 1.0 V thermal noise-canceling amplifier using 0.13 mum CMOS technology. The amplifier consists of a CMOS inverter-based transimpedance amplifier, and a noise-canceling circuitry. The thermal noise-canceling circuitry is very simple, and consists of only two CMOS inverters. The simulation result shows the input referred noise of the proposed amplifier is 3 nV/radicHz,...
This paper described the design of generalized partial-response (GPR) target and its corresponding equalizer for perpendicular magnetic recording (PMR) read channel with jitter noise. In this design the readback signal model uses transition response that its parameter is calculated based on media properties and reader head geometry specifically designed for 1 Tb/in2 areal density. The GPR targets...
