60 GHz 5-bit digital controlled phase shifter in a digital 40 nm CMOS technology without ultra-thick metals

A 5-bit digital controlled switch-type passive phase shifter realised in a 40 nm digital CMOS technology without ultra-thick metals for the 60 GHz Industrial, Scientific and Medical (ISM) band is presented. A patterned shielding with electromagnetic bandgap structure and a stacked metals method to increase the on-chip inductor quality factor are...

Reconfigurable subsampling receiver architecture for wireless body area networks

The wide range of wireless body area network (WBAN) applications gives rise to different system requirements for the carrier frequencies and data rates. In order to accommodate various standards in WBAN applications, a universal receiver system with good performance and low power is highly desirable. The subsampling receiver architecture is one...

Power-aware architecting for data-dominated applications

The task of the system architect is to take the correct early decisions despite the uncertainties. Power-Aware Architecting provides a systematic way to support the system architect in this job. Therefore, an iterative system-level design approach is defined where iterations are based on fast and accurate estimations or predictions of area,...

A Quantized Analog Delay for an ir-UWB Quadrature Downconversion Autocorrelation Receiver

A quantized analog delay is designed as a requirement for the autocorrelation function in the quadrature downconversion autocorrelation receiver (QDAR). The quantized analog delay is comprised of a quantizer, multiple binary delay lines and an adder circuit. Being the foremost element, the quantizer consists of a series of comparators, each one...

A Delay Filter for an ir-UWB Front-End

A continuous-time analog delay is designed as a requirement for the autocorrelation function in the quadrature downconversion autocorrelation receiver (QDAR). An eight-order Fade approximation of its transfer function is selected to implement this delay. Subsequently, the orthonormal form is adopted, which is intrinsically semi-optimized for...
