“…Notice that the output spectrum contains notches at 4.76 and 7.67 GHz below 10 GHz (data null). For applications in high-speed data communication through PCB or copper cable, discontinuities such as connectors or via usually create notches in frequency domain by a destructive interference mechanism [20, 21]. However, for waveguides under coherent architecture, a non-linear propagation constant, which is a complicated function of waveguide geometry, length, dielectric material, and carrier frequency, generates notches in frequency domain after down-conversion.…”

An impulse response method is carried out to analyze waveguide's information capacity within a coherent communication system. Such capability is typically estimated according to group delay variations (seconds/bandwidth/distance) after carrier-modulated data undergoes a dispersive medium. However, traditional group delay methods often ignore non-linear effects by assuming input data stream only occupies narrow bandwidth such that a propagation constant can be linearized centered at the carrier frequency. Such a constraint can be lifted with a proposed baseband equivalent impulse response method by using frequency domain convolution and multiplication. Once the impulse response in frequency domain is secured, its time domain counterpart can be calculated based on inverse Fourier transformation. Such analysis can fully reveal data pulse's broadening and gauge its inter-symbol interference by simply convolving input data with extracted impulse response, not limited to specific frequency range or type of waveguide.

“…However major issues of current mobile interface such as limited bandwidth, higher power consumption, and non‐reconfigurable data access are bottle necks in improving energy efficiency and bandwidth [2]. Recent research [3] has demonstrated a tri‐band transmitter by combining two 64‐QAM RF‐band transmitters (RFTX) and an 8‐PAM (pulse‐amplitude modulation) baseband transmitter. However, it will be very challenging to design an on‐chip receiver for this complicated transmitter, therefore it used instrumental receiver [3].…”

The proposed multi-band multi-modulation I/O (MMI) for mobile memory interface consists of two RF-band and 4-PAM (pulseamplitude modulation) transceivers for simultaneous bidirectional read/write operations on a shared single-ended 5 cm off-chip transmission line. A novel band-selective transformer is introduced to combine and split two amplitude shift keying modulated RF-bands with a 4-PAM baseband for transmitting and receiving multiple data concurrently. The MMI interface consumes 2.8 pJ/b from a 1.2 V supply voltage. Testing results show that the MMI interface achieves an overall data rate of 14 Gb/s/pin. It is implemented in a 65 nm CMOS process with chip area of 0.25 mm 2 .

Abstract-With the ultra-scaling of CMOS technology, high-speed and low-power millimeter-wave communication systems for network-on-chip have been attracting more and more attentions due to the wider bandwidth and higher data rate that can meet the ever-increasing needs for multimedia, massive external data storage, or even biomedical applications. However, from manufacturing's perspective, the circuits implementations are increasingly susceptible to fabrication process variations with the scaling of CMOS technology, which results in loss of yield rate. To solve this issue, a sensor-fusion solution is proposed in this paper by adding multiple on-chip sensors, including power detectors, temperature sensors, information envelope detectors and related filters, instrumentation amplifiers using a standard CMOS process. These sensors and detectors aim to collect critical system performance and environmental parameters, which will be utilized by a self-healing and optimization algorithm to adjust the state of system components by digitized control knobs.
