Driven by a high data rate and need for efficient spectrum utilization, modern communication standards like MoCA usually feature OFDM which has a high peak to average power ratio (PAPR). This constrains the designers to resort to the most linear version of PA, a Class-A PA. In addition to having a poor maximum efficiency, a Class-A PA’s efficiency degrades rapidly under back-off. On the other hand, a Class-B PA, albeit very non-linear compared to a Class-A PA, has a higher maximum efficiency and it degrades less rapidly under back-off. Similar to the idea of pre-equalization used in communication, the input signal of the PA could be pre-distorted effectively to compensate for its non-linearity. In standard CMOS process, particularly with technology downscaling, the cost of digital signal processing has reduced dramatically, making it a smart choice to implement the pre-distortion in the digital domain.

Having been deprived of this Madras Style Kurma for 2 years now, I have learnt to make this amazing dish , purely out of desperation. I thank Abinesh for teaching me this recipe. Folks, it tasted better than any "South Indian restaurant in the US" could offer. Following is the recipe. Ingredients 1) Scraped Cocunut - 50g 2) Fennel Seeds - 1 table spoon 3) Channa Dal - 50g 4) Tomatoes -2 5) Onions - 2 6) Ginger-Garlic paste - 3 tbl spoon 7) Cloves - 3 8) Cinnamon - half a stick 9) Turmeric powder - 1 tea spoon 10) Sambar powder - 3 table spoon 11) Salt - As per personal taste (roughly 1 table spoon) 12) Vegetables - Cauliflower/ Peas Procedure 1) Cocunut, channa dal and fennel seeds are ground to paste. 2) On a frying pan, oil is heated. Cloves and cinnamon are added to the oil. 3) Finely chopped onions are cooked (till golden brown), followed by the addition of ginger-garlic paste. 4) After the raw smell of ginger-garlic is gone, boiled vegetables are adde
