Overview

The TS_IREF_88uA_X8 is a current reference biasing circuit which provides a sink/source ZTAT (zero-toabsolute temperature) temperature-independent current from 250nA up to 88μA and supplied with 3.3V. As shown in Figure 1, the current reference circuit consists of a bandgap circuit generating a ZTAT voltage 𝑉𝐵𝐺 and by using an OTA, an NMOS transistor, and a trimmed P-doped poly resistor (temperature independent), a ZTAT current can be generated and copied using current mirrors. The bandgap voltage 𝑉𝐵𝐺 is also provided as an output in case it is needed as a reference voltage. Digital trimming is available for the generated current through trimming bits. The current reference also provides an Enable signal to control whether to turn on or shutdown the bandgap circuit and consequently the biasing circuit.

Analog and Power Management Trends in ASIC and SoC Designs

The design of modern Application Specific Integrated Circuits (ASICs) and Systems on a Chip (SoCs) in advanced process nodes can be differentiated by the on-die integration of analog functions, such as power management. Vidatronic offers this white paper to give some historical background on this trend and delve specifically into the integration of power management. Vidatronic IP solutions and the benefits they bring to ASIC and SoC designers are discussed.

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).

Silicon Qualified SuperViC: the only way to safe SoC integration

System integrators often encounter problems on application boards too late in the design cycle, when bringing together Virtual Components (ViCs of silicon IPs) into a system. Some ViC performances may be degraded at higher levels (SoC and PCB), and thus the final system does not perform as well as expected. In other words, assembling high-performance ViCs together does not guarantee high-performance SoCs or systems when fundamental integration aspects are not addressed or key issues are violated during the integration process.

Presented in this paper is a tool that automatically migrates analog designs from one process to another while keeping circuit and layout topologies.
