Abstract

A 533 MHz programmable phase-locked loop is designed for DDR applications using a switched current filter and implicit phase detection. The use of switched current technology allows a fully integrated loop filter which is much smaller than equivalent integrated passive filters, as a result the circuit occupies only 0.012 mm(2) on a 0.12 mm 1.2 V digital CMOS process.
