In this paper, we present a digital filter, which is used to establish an interface between oversampling sigma-delta modulator and direct torque controller (DTC), for closed-loop motor control system. The destination of this digital filter is to decrease the frequency spectrum and filtered out the feedback signal into the DTC. Note that the architecture of(More)
This paper presents the design and implementation on a new architecture of broadband network system which suitable for asymmetric digital subscriber line (ADSL) application. The main design skill is based on the cell-based digital IC design process, and is implemented in 0.18 µm 1P6M CMOS process. The main function of this chip is to build a bridge(More)
This paper presents the design and implementation of an ASIC of the Ethernet-ATM Bridge which is fabricated in UMC 0.18 μm 1P6M CMOS process. The main function of this chip is to build a bridge between Ethernet and ATM which is not only to merge three chips into a single chip, but also to give up the RISC processor. This development will enhance the(More)
