By Diksha Nama, contributor, Engineers Garage An audio system is designed to receive audio signals (via microphone), record audio in some storage, transmit audio (through wired or wireless communication channels), and reproduce audio signals (via speakers). So, the audio circuits perform signal processing for representing the sound in the form of electrical signals, manipulate the […]

The ABCs of functional verification techniques
By Aijaz Fatima of Siemens business Functional verification is the process of demonstrating the functional correctness of a design with respect to the design specifications. Functional verification does not confirm the correctness of the design specification and assumes that the design specification is correct. It is one of the most challenging steps of the IC […]

Designing a DAC-controlled, high-side constant current source
by KlausST, supermoderator on EDABoard.com Here I’d like to show how to design a DAC controlled high -side constant current source. Since it is often used as 0..20mA (or 4..20mA) current loop interface, we will focus on the interface requirements. * low speed ( maybe some 10Hz up to some kHz) * high precision * […]

The new broadband microwave RF conical inductors from Gowanda Electronics – the C070 – are available in Surface Mount (C070SM) and Flying Lead (C070FL) configurations to enhance utility in the electronics design community, especially for communication applications. The C070 series was developed to address market needs and industry trends calling for ever-increasing performance from broadband […]
Low-power DAC with NVM simplifies handheld designs
Implementing multi-channel system control or signal outputs using Digital-to-Analog Converters (DACs) in today’s portable and handheld industrial, communications, consumer and medical systems has been difficult to do without significant processor overhead for device configuration during power-up. Microchip Technology Inc. announced a solution to this problem with its MCP47/48FxBx8 family of octal 12-bit DACs, the first of their […]
Analog multiplexers capable of switching signal voltages up to 36 V
Diodes Incorporated announced the introduction of the PS508 and PS509 analog multiplexers that are capable of switching signal voltages of up to 36V in an industrial environment. The high voltage capability of the devices will support industrial IoT (IIoT) applications using multiple sensors, including factory automation and process control, battery monitoring systems, and test and […]
