by Janet Heath, contributing writer Assuming that you are familiar with the fundamental specifications of an ADC and what they mean, the next step is to know your entire signal…
The post Choosing between a Sigma-Delta ADC vs. SAR vs. Pipeline appeared first on Analog IC Tips.
Modulation is considered to be a radio frequency (RF) technique which refers to modifying a periodic waveform with another waveform. For example, frequency modulation takes an RF “carrier” signal (sine wave) at say 88MHz and varies the frequency slightly, based on your “modulating” signal which will most likely be an audio signal up to 15kHz […]
Magnetic sensors are typically Hall effect sensors (named after Edwin Hall who discovered the effect in 1879), whereby a small voltage difference can be measured across a conductor with current flowing through it when a perpendicular magnetic field is applied. They are available as small, integrated solutions with signal or multiple outputs, and analog or […]
In battery operated devices which have removable batteries, you usually need to prevent the batteries from being connected the wrong way round to prevent damage to the electronics. If that is not possible by physical means you need to include some electronic protection. Physical protection can simply mean a polarized connector or a battery with […]
I recently came across the TDK SESUB-PAN-T2541 Bluetooth module. It is a complete bluetooth module consisting of a Texas Instruments CC2541 Bluetooth “System-on-Chip” (SoC) and the peripheral components required to use it – crystal, balun, and 15 other passive components. While it initially doesn’t sound that remarkable, when you look at the size (4.6mm x […]
A “voltage reference” can mean anything from a simple resistive power supply rail splitter as a virtual ground for an opamp, to a high precision, low drift, low noise reference voltage for an analog to digital converter (ADC). For an opamp virtual ground, a couple of resistors and a capacitor can work and you may […]
I frequently design new electronics systems. Sometimes these are variations of something I have done before and at other times they are completely new. If you are new to a particular product area and there is something similar in the marketplace then it is always a good idea to have a look at how other […]
Summary This article discusses the newly emerging specifications, USB Type-C and Power Delivery (PD). Part 1 will introduce the USB 3.0 specification and its capabilities. Part 2 will explain various aspects related to the design of Electronically Marked Type-C cables. Introduction The USB Type-C is the newly introduced cable for USB. It is a simple, […]
Power supply noise can come in more than one form. It could be switching noise from a switching regulator or switched mode power supply or noise from a linear regulator. While switching noise is to be expected, linear regulators are often assumed to be “quiet” but they may not be as quiet as you think. […]
Unless you are an RF designer you probably haven’t thought much about intermodulation distortion. Harmonic distortion is more likely to have been of concern with low frequency circuits such as video and audio. Harmonic distortion, as the name suggests, creates unwanted components which are harmonically related to the signal. So, if you are amplifying 1kHz […]
