We have developed a current mode cyclic analog-to-digital converter using a 0.8 m CMOS process. Our circuit structure makes it possible to construct the converter without any precise analog components, hence, it is well compatible with submicron processes. The fabricated circuit has an area of 0.014mm2 and performs 8-bit resolution at a sampling rate of 40kHz and average power dissipation of 37...

This paper presents a sample-and-hold circuit based on a novel implementation of the bootstrapped low-voltage analog CMOS switch. The heart of this circuit is a new low-voltage and low-stress CMOS clock voltage doubler. Through the use of a dummy switch, the charge injection induced by the bootstrapped switch is greatly reduced resulting in improved sample-and-hold accuracy. Simulation results ...

Emerging non-volatile memory (NVM), or memristive, devices promise energy-efficient realization of deep learning, when efficiently integrated with mixed-signal integrated circuits on a CMOS substrate. Even though several algorithmic challenges need to be addressed to turn the vision of memristive Neuromorphic Systems-on-a-Chip (NeuSoCs) into reality, issues at the device and circuit interface n...

In this work we present a full analog turbo decoder for hard-disk EPR-IV read channels in CMOS technology. The design is based on a current-mode approach developed by Loeliger et al. [1], for the analog implementation of sum-product algorithms. The circuits main attractions are the coding gain offered by turbo codes over the uncoded EPR-IV channel, and the relative simplicity and power efficien...

The oscillation-test strategy is a low cost and robust test method for mixed-signal integrated circuits. Being a vectorless test method, it allows one to eliminate the analog test vector generator. Furthermore, as the oscillation frequency is considered to be digital, it can be precisely analyzed using pure digital circuitry and can be easily interfaced to test techniques dedicated to the digit...
