Using Deep N Wells in Analog Design
2015年5月7日 · In this case, the deep N well is formed by a high energy ion implantation to give peak impurity concentration deep enough to un-affect the NMOS device performance 1.Connection to the deep N well is formed by a N well ring that is connected to VDD.
An Analog Tutorial: Current sources - Planet Analog
2019年3月28日 · James Bryant, retired Analog Devices ‘guru’ says, “…current outputs offer advantages in a number of situations, including analog current-loop signaling (0 mA to 20 mA and 4 mA to 20 mA) in high-noise environments, and level shifting an analog signal across a large potential difference without the use of optical or magnetic isolation techniques.” (See Reference 4)
The Basics of SerDes (Serializers/Deserializers) - Planet Analog
2010年9月16日 · In a serial bus, a device called SerDes (Serializer/ Desrializer) is used to transmit and receive data over the serial link. In essence, a SerDes is a serial transceiver which converts parallel data into a serial data stream on the transmitter side and converts the serial data back to parallel on the receiver side.
Planet Analog - All Signal No Noise
Planet Analog provides an online community for semiconductor and system designers/engineers interested in advancing analog design techniques.
Layout Dependent & LOD Effects in Analog Design
2014年10月9日 · Analog designers have always had to worry about physical layout to get good matching of devices. Variations in doping levels across the chip, usually assumed to be in a gradient in one or two dimensions, could be handled by …
Matching in Analog Layout
2014年5月20日 · Analog circuits often use structures like differential pairs and current mirrors, where the matching of device characteristics such as the threshold voltage V t is important. Circuits using these structures with device threshold differences of a few millivolts or less can determine the performance and yield of a design.
An SoC-like design model for the analog world? - Planet Analog
2024年11月18日 · Is the system-on-chip (SoC) model that emerged in the semiconductor industry more than two decades ago seeping into the analog world? It seems like that when you take a closer look at onsemi’s recently announced Treo platform. It’s an analog and mixed-signal platform built with bipolar-CMOS-DMOS (BCD) process technology on a 65-nm node.
Why 45 degrees? An overview of loop stability in operational …
2024年11月26日 · In operational amplifier stability, one rule of thumb is to allow 45 degrees of phase margin. Other design guidelines state that 60 degrees is best; still others say that 30 degrees is sufficient.
Put away that hot iron and try resistance soldering
2024年12月17日 · The image of the electrical engineer or hacker bent over and using a soldering iron on a circuit board is a classic visual cliché on TV and movies (Figure 1).Figure 1 The electrical engineer working on a circuit board with a soldering iron is an often-used image, with considerable truth.
