This paper describes a current-steering Digital-to-Analog Converter (IDAC) architecture with a novel switching scheme, designed for GPON Burst Mode Laser Drivers (BMLD) and realized in a 0.35 μm SiGe BiCMOS technology with 3.3 V power supply. The (4+6) segmented architecture of the proposed 10-bit IDAC is optimized for minimum DNL (Differential Nonlinearity). It combines a 4-bit MSBs (Most Sign...

Millimeter-wave wireless communication systems have considerably gained in importance in recent years. Important applications as 60-GHz WLANs and WPANs, 80-GHz automotive radar, and 94 GHz imaging have emerged, requiring significant effort on the design of transceiver's silicon-based integrated circuits. In this context, integrated transformers are of a particular interest. They may perform, am...

Broadband signal generation and radiation is demonstrated based on an oscillator-less Direct Digital-to-Impulse (D2I) picosecond pulse radiator with 153GHz 3dB-BW (252GHz 10dB-BW) centered at 140GHz. The radiated pulse achieves a peak EIRP of 15dBm and peak radiated power of 2.5mW. It is shown that the starting time of the radiated pulse is locked to the edge of an input digital trigger with a ...

We all know that the basic building block of any communication system is the reference voltage generator. The objective of reference generation is to establish a DC voltage or current that is independent of the supply and process and has a well-defined behavior with temperature. Band Gap Reference (BGR) is one of the most popular reference generators. In the conventional BGR circuit, the refere...
