Overview

The MVCT018 is a programmable and very accurate capacitance-to-digital converter interface, designed to be easily integrated with capacitive sensors. The chip features very fast measurement times, low operating power, and very low standby currents, making it very suitable for low power and portable applications. The ASIC includes a high-accuracy integrated temperature sensor that enables the user to compensate for temperature dependencies of sensor elements, as needed.

How to specify and integrate successfully a measurement analog front-end including its power computation engine in an energy metering IC

Based on the system specification of a typical smart meter, this article demonstrates the importance of carefully selecting the power metering IP solution so that its specification matches the standard requirements and copes with the application challenges. This article then pinpoints thoroughly the various issues that must be taken into account for the selection of the Silicon IP and helps identify the possible trade-offs between the performance of the Mixed-signal Front-end (MFE) and that of the Power and energy Computation Engine (PCE).

Modeling and Verification of Mixed Signal IP using SystemVerilog in Virtuoso and NCsim

In this paper we present a methodology to model and verify a mixed-signal IP using SystemVerilog in Virtuoso and NCsim. We take our 12.5Gbps transmitter (TX) design as an example to explain the method we propose. This TX is designed to operate at programmable data rates from 1.25Gbps – 12.5Gbps and to support requirements of multiple serial protocols like USB, PCIe, and SATA. Interaction between AFE and Digital is key towards proper implementation of features like Feed Forward Equalization (FFE), programmable output swing and power management states.

Is there a "one-size fits all" SOC PLL?

Like most types of circuits, there is no such thing as a "one size fits all" PLL. This article will explore the trade-offs in PLL performance and design and look for a solution to most SOC PLL needs.
