A successive-approximation ADC with non-binary code achieves 55dB SNR at sampling frequencies up to 20MHz. The converter, with on-chip driver for analog input and reference input, measures 0.08mm/sup 2/ in a standard 0.13/spl mu/m CMOS process and consumes 12mW from a single 1.2V supply.
The constantly growing quest for global roaming with a fast mobile internet access has further increased demand for multiband 3G cell phones supporting also 2G/2.5G standards, in order to provide full coverage any time, any place. In order to substantially reduce cost and size of the multimode, multiband handsets, it is necessary to develop a transmitter… (More)
Battery operation in mobile applications needs power efficient DC-DC converters which are able to handle battery voltages up to 5.5V. Normally, these DC-DC converters are built in special technologies. For decreased footprint and chip count of the overall system, a system-on-chip solution on modern CMOS technology with core supply voltages around 1V is… (More)
The evolving trend for increasing data rates in cellular communication systems with limited and fragmented frequency spectrum requires enhanced spectral efficiency of today's and future communication standards. The resulting need for high-order modulation schemes with large peak-to-average power ratio results in stringent requirements on in-channel… (More)
This paper wants to clarify the important design parameters of the 45 nm process like matching, flicker noise, and offset from an analog designers' point of view. This paper describes a continuous time DeltaSigma ADC for voice coding applications.
A mixer and operational amplifier filter combination in 65 nm CMOS technology for DVB-H is presented. Special focus is laid on the design of the operational amplifier, which is a nested-Miller compensated, 3-stage feed-forward operational amplifier. Characteristic of the operational amplifier is the supply voltage of 2.5 V to enlarge the output signal swing… (More)
