Abstract :
We proposed the use of power distribution network (PDN) of a microprocessor for ubiquitous access of internal nodes for test/debug and showed the suitability of impulse ultra-wideband (UWB) communications for the purpose. This paper presents design of a data recovery block to recover data from UWB impulses superposed on a power line of a microprocessor. Considerations for data recovery block design based upon measured PDN characteristics have been discussed. The proposed circuit was implemented in TSMC 0.18 um CMOS process, and simulations show that it consumes 4.42 mW when operating from a 1.8 V supply and at a pulse repetition rate of 200 MHz.
