A new architecture is presented for a single-chip tuner for digital terrestrial television, based on existing double conversion and direct conversion topologies. The new design forms part of a mixed-signal Digital Video Broadcasting–Terrestrial (DVB-T) receiver system, employing digital signal processing at baseband to ensure minimal performance requirements for the analog circuitry. To evaluat...

The predominant view of embryonic development and cell differentiation has been that rigid and even irreversible epigenetic marks are laid down along the path of cell specialization ensuring the proper silencing of unrelated lineage programmes. This model made the prediction that specialized cell types are stable and cannot be redirected into other lineages. Accordingly, early attempts to chang...

The 7GHz unlicensed band around 60GHz provides the possibility of gigabit-per-second wireless communications. In addition to satisfying speed-intensive applications, such high data rates can also reduce the energy dissipated per bit because the power consumption of RF transceivers has historically increased sublinearly with the data rate. Moreover, the millimeter wavelength permits the integrat...

Memories are most important building blocks in many digital systems. As the Integrated Circuits requirements are growing, the test circuitry must grow as well. There is a need for more efficient test techniques with low power and high speed. Many Memory Built in Self-Test techniques have been proposed to test memories. Compared with combinational and sequential circuits memory testing utilizes ...

We present work toward the development of a digital to analog (DAC) conversion scheme to efficiently achieve the bit-depths required in high performance infrared scene projection. This is achieved by appropriately dividing the conversion amongst the close support electronics (CSE), the periphery of the read-in integrated-circuit (RIIC) chip, and the pixel drive circuitry.

— This paper is focused on equipping wireless devices (including sensors) with novel, high efficiency circuitry to harvest and convert ambient RF power to direct current (dc). Key components of this technology are (a) miniaturized antenna and (b) high efficiency rectifying circuit. The first is responsible for capturing the RF waves, and the latter coverts the RF energy to dc. A major challenge...

A direct conversion modulator-demodulator with even harmonic mixers with emphasis on noise analysis is presented. The circuits consist of even harmonic mixers (EHMs) realized with antiparallel diode pairs (APDPs). We evaluate the different levels of I/Q imbalances and DC offsets and use signal space concepts to analyze the bit error rate (BER) of the proposed transceiver using M-ary QAM schemes...
