Abstract :
In this paper we describe a 20 MHz sample rate switched-current finite impulse response (FIR) filter, suitable for equalizer architectures. The basic cell of the FIR filter is the switched-current (SI) sample-and-hold (S/H) circuit, appropriate for low voltage operation. The programmability of the FIR filter structure is achieved via MOSFET-only current dividers (MOCD). The FIR filter has been designed using the AMS 0.8 μm CMOS process. The power consumption per tap is 12 mW at ±1.5 V power supply
