A novel CMOS all-pass tunable phase shifter


A new current mirror based all-pass, tunable phase shifting technique is proposed and simulated in 0.18um CMOS, after a brief introduction on phase shifter applications, and comparison between different implementation methods. In the new current-mode approach, cut-off frequency of transistor is the operational limit of the proposed phase-shifter… (More)
