Abstract
This paper presents a CMOS RF second-order voltage-mode all-pass filter (APF) as a time delay cell. The proposed filter benefits from a simple structure; consisting of one transistor, three resistors, and one grounded capacitor and inductor. The filter reaches a group delay of 60 ps over a 10 GHz bandwidth, while achieving maximum delay-bandwidth-product (DBW) and it consumes only 10.3 mW power. On the other hand, an active inductor is used in the APF instead of a passive RLC tank in order to co...
