چکیده

A new automatic tuning circuit based on synchronous rectification scheme is proposed and functions in the idle periods between the burst-mode transmissions. The proposed CMOS tuning circuit can be fully integrated with the front-end filter. Simulation results employing 0.5μm CMOS technology have verified that the center frequency is automatically tuned to 1.25GHz with 10% process variation presence. The deviation is 15MHz, representing to only 1.2% error.

Real-time Automatic Tuning of the Centre Frequency and the Q- Factor in CMOS LC Filters

CMOS analogue filters can be implemented with several structures including active-RC, transconductance-C, MOSFET-C, and LC filters. CMOS LC filters have the advantage of being less sensitive to parasitic capacitances as they can actually be absorbed into the total reactance required for the design frequency [1]. This enables them to be utilized in gigahertz range applications; however, on-chip ...

A single-chip CMOS IF-band converter design for DVB-T receivers

This paper describes a CMOS single chip IF-band converter (IFC) which is applied in the analog front end circuitry of DVB-T receivers. The proposed IFC is composed of a down-conversion mixer, an automatic gain controller (AGC), and an anti-aliasing filter (AAF). The down-conversion mixer uses a current folded-mirror technique which converts a 36 MHz intermediate frequency (IF) input into a 4.5 ...

The Design of a 3-V 900-MHz CMOS Bandpass Amplifier

A new bandpass amplifier which performs both functions of low-noise amplifier (LNA) and bandpass filter (BPF) is proposed for the application of 900-MHz RF front-end in wireless receivers. In the proposed amplifier, the positive-feedback Q-enhancement technique is used to overcome the low-gain lowQ characteristics of the CMOS tuned amplifier. The Millercapacitance tuning scheme is used to compe...
