In this context, it is highlighted the importance of strategies alignment and mutual reinforcement between MNC headquarters and subsidiaries in the supply management. The aim of this article was to analyze how foreign multinational company subsidiaries operating in emerging markets like Brazil are embedded and attend MNC global sourcing strategies. A multiple case study research has been conducted in eight Brazilian subsidiaries of MNC through in-depth interviewing with local supply managers and a documentary research was made. It was identified that Brazilian production subsidiary participation is partially aligned with the strategy of MNC global sourcing. The results suggest that subsidiaries in emerging markets should review its approach related to the global sourcing management, becoming more proactive, aligned with the MNC global sourcing strategy, as well as serving in their level of expertise.

The advantages of the proposed topology are simplicity and feasibility of low-power and low-voltage operation. Experimental results in a 0.35 µm CMOS prototype indicate 1 mA consumption for 1MHz bandwidth, and distortion level below 1% for an input current equal to 80% of the full scale range. The multiplier area is around 10,000 µm 2. I.
