This paper investigates the design of phase locked loops (PLLs) using the switched current (SI) technique and proposes a novel 2nd order PLL architecture that does not require an explicit phase detector, unlike conventional PLL circuits. Simulated results based on 0.35μm BSim3v3 CMOS models of two PLL designs (10MHz FSK demodulator, 500MHz frequency synthesizer) are included.
