Abstract :
We describe an approximately-PTAT CMOS current reference circuit that is useful for large analog systems. An innovative capacitively-coupled startup circuit that draws no static power is also presented. Experimental results from 0.5 mum and 0.18 mum implementations are shown. Both references are cascoded and use no resistors. The 0.18 mum version operates down to VDD = 0.5V
