This paper presents a 10-Gb/s low-power adaptive continuous-time linear equalizer, which automatically determines the optimal equalization condition by searching for the equalization coefficient producing the largest peak value in histograms obtained with asynchronous under-sampling. To reduce the power consumption, the integrated digital controller turns off the circuit blocks used for the ada...

This brief presents the architecture and implementation of an analog processor, which in a way akin to a digital microprocessor, embodies a physical model of the universal Turing machine. The analog microprocessor (A P) executes software programs, while nevertheless operating on analog sampled data values. This enables the design of mixed-mode systems which retain the speed/area/power advantage...

This paper presents a general-purpose sampled-data analogue processing element that essentially functions as an analogue microprocessor (AμP). The AμP executes software programs, in a way akin to a digital microprocessor, while nevertheless operating on analogue sampled data values. This enables the design of mixed-mode systems which retain the speed/area/power advantages of the analogue signal...

Currents injected by CMOS digital circuit blocks into the power grid and into the substrate of a system-on-a-chip may affect reliability and performance of other sensitive circuit blocks. To verify the correct operation of the system, an upper bound for the spectrum of the noise current has to be provided with respect to all possible transitions of the circuit inputs. The number of input transi...

The recent explosion of interest in wireless personal communication systems motivates the development of fully integrated radio receivers. The parallel reduction of the dimension in CMOS technology, and hence higher levels of integration enables the combined integration of bandpass or baseband analog-to-digital converter along with the traditional front-end receiver building blocks. While this ...

An adder is a digital circuit that performs addition of numbers and it plays an important role in today’s digital world. In processors and other kinds of computing devices, Adders are used in the arithmetic logic units. They are also utilized in other parts of the processors for calculating addresses, table indices, increment and decrement operations and other similar operations because it is t...

A fully integrated GMSK modulator in DRRS band is presented. All components of the transmitter except the power amplifier, including the loop filter and the oscillator are on-chip.

A CMOS sub-circuit that is able to improve data communication is described. It removes jitter and hence improves the eye diagram of high-speed digital data signal. The circuit is based on a delay-locked loop and uses a half-frequency reference clock. The prototype circuit is fabricated in 2.5 V, 0.25-μm CMOS and occupies an area of only 270 x 50 μm. It is demonstrated that at 900 Mbit/s NRZ dat...

We propose a CMOS circuit that can be used as an equivalent to resistors. This circuit uses a simple differential pair with diodeconnected MOSFETs and operates as a high-resistance resistor when driven in the subthreshold region of MOSFETs. Its resistance can be controlled in a range of 1–1000 MΩ by adjusting a tail current for the differential pair. The results of device fabrication with a 0.3...
