The Basics of SerDes (Serializers/Deserializers) - Planet Analog
WEBSep 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.
Matching in Analog Layout - Planet Analog
WEBMay 20, 2014 · Matching in Analog Layout. 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.

ADC Guide, Part 12: Input Configurations; Single-Ended
WEBMar 12, 2013 · Differential ADC. The primary advantage of differential ADCs is high common-mode noise immunity compared to single-ended ADCs. This noise immunity is due to: 1) the same noise being coupled on both the inverting and non-inverting input signals of the ADC; and 2) this noise is rejected by common-mode rejection capabilities of the differential ADC.
The Gold Standard of Analog Circuit Prose
WEBFeb 15, 2013 · The K2-W used power supplies of +300V for the tube anodes, -300V for the cathodes and grid bias, and 6.3VAC (or DC) for the filaments.

Layout Dependent & LOD Effects in Analog Design
WEBOct 9, 2014 · This stress affects carrier mobility in the devices and, hence, current. This is known as “length of diffusion” or LOD effect, where the characteristics of a device vary according to the distance of its gate from the diffusion edge. To design with LDE effects, various layout techniques can be used: Use similar diffusion size, shape ...
