An Analog Tutorial: Current sources - Planet Analog
Mar 28, 2019 · 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
Sep 16, 2010 · 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.
An SoC-like design model for the analog world? - Planet Analog
Nov 18, 2024 · 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 …
Nov 26, 2024 · 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.
