Abstract

Interchip data transmission was demonstrated using impulse radio ultrawideband complementary metaloxide-semiconductor (CMOS) transmitter integrate circuits with on-chip dipole antennas. A differential pseudorandom binary sequence of 2 7 data of Gaussian monocycle pulse (GMP) was formed by 65-nm CMOS logic circuits using up-and downpulses with certain gate delays. The CMOS transmitter generated 5-Gb/s GMP with the center frequency of 10 GHz. To improve transmission gains, an interposer with the high dielectric constant (ε r = 38) and optimized thickness was inserted under the CMOS chips as a dielectric slab waveguide. 2-Gb/s GMP signals were transmitted and received in the distance of 10 mm by use of the CMOS on-chip antennas and the high-κ interposer.Index Terms-Complementary metal-oxide-semiconductor (CMOS), Gaussian monocycle pulse (GMP), interposer, on-chip antenna, pseudorandom binary sequence (PRBS), transmitter, ultrawideband.

Microwave Imaging Using CMOS Integrated Circuits with Rotating 4 × 4 Antenna Array on a Breast Phantom

“…Photographs of this system are shown in Figures 1(a) and 1(b). In this system, Gaussian monocycle pulse (GMP) trains which have the pulse width of 160 ps, the center frequency of 6 GHz, and the repetition rate of 100 MHz is generated by a transmitter-chip (Tx-chip) [29,30] and transmitted by a Tx module as shown in Figure 2. Figures 2(a) and 2(b) show Tx-chip wire bonding and a top view of Tx module, respectively.…”

“…Therefore, miniaturization of the imaging system is essential for widespread use [21][22][23]. In our previous work, functional CMOS integrated circuits were developed for Gaussian monocycle pulse generation, highspeed sampling, and channel switching [24][25][26][27][28][29][30]. Additionally, a complete imaging system using these CMOS circuits was proposed and the feasibility was examined [31].…”

Ultra‐short pulse generator using 0.13‐μm CMOS

“…Compared with continuous wave, high frequency pulse is a promising candidate for communications because of its simplicity in circuit design and low power consumption . Recently, a 10 GHz center‐frequency Gaussian pulse generated by using 65‐nm logic complementary metal‐oxide‐semiconductor (CMOS) process has been reported, and ultra‐wide band (UWB) pulses have also been demonstrated . Logic gates as well as under‐damping state of R‐L‐C circuit have been adopted to generate pulses.…”

Transmission Performance Investigation of IR-UWB Signals over Existing optical fiber Transmission link

“…Here, information is carried in a set of narrow pulses of electromagnetic energy where the bandwidth is approximately proportional to the pulse width [4,6]. Different applications based on IR-UWB communication have been emerged such as wireless body sensor networks [5], interchip data transmission [7], high resolution ranging system [8,9], wireless sensor network synchronization [10], and in-building network applications [1]. These applications are driven by the progress reported in the design of IR-UWB transmitters capable of shaping the power spectrum of the UWB signal to mitigate mutual interference [11,12] and receivers with narrow band interference mitigation capabilities [13,14].…”
