Matching in Analog Layout
May 20, 2014 · One common matching technique is known as common centroid. In this case, two devices to be matched are split into several fingers and placed in a pattern, as shown in Figure 1. The key points are that the centroids of each device should coincide, the devices should be symmetrical, their orientation should be the same, and the array should be as ...
Electrically Correct Analog Layout
Mar 17, 2017 · Electrically Correct Analog Layout. Analog IC layout relies on the schematic as a starting point, conveying not only information about the connectivity of the devices in the circuit, but also the design intent. Traditional approaches have been to use the DRC (design rule check), ERC (electrical rule check) and LVS (layout versus schematic ...
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)
Build Your Own Curve Tracer, Part 1: Introduction - Planet Analog
Jan 14, 2017 · The SMU shown above has a current sense circuit (ISN) that is a high-side circuit (ISN-H) because the sense circuit is in series with the positive or high-side terminal. The TPA202 input-port (INP) SMU has high-side current sensing and the output port (OUT) has low-side current sensing (ISN-L), where the OISN circuit is between the negative port terminal and the amplifier or source ground.
A short primer on RF-over-fiber designs and applications
Jul 7, 2022 · In simplest terms, it’s an all-analog way to transfer extremely high-frequency signals—what we conveniently call RF—from point A to a point B many meters away by using optical fiber rather than the more-common coaxial cable, which is called RF over coax/cable, or RFoC. The RF signal of interest can be in the multi-gigahertz range and the ...
Planet Analog - All Signal No Noise
6 days ago · A vast array of on-chip LDO options and characteristics can make the selection process complex. As quantum computers continue to evolve, the demand for high-fidelity, low-noise, and high-speed analog components will become more critical.
PWM Pulse Width Modulation; Basics and Some Advanced Concepts
May 10, 2017 · Pulse Width Modulation (PWM) is a basic concept that is employed in many areas of electronics. PWM is a simple averaging method that is used in everything from microwave power percentages to LED dimming. The methods of implementation are also simple yet there are aspects that are quite complicated. One of the simplest ways to explain PWM is ...
The state of analog design industry in 2021 and beyond
Oct 6, 2021 · Mark Waller, director of the user enablement at Pulsic, echoed Balch’s views on the current state of analog design. “For some time, analog design has been focused on analog circuits as the interface between the real world and the digital,” he said. “However, the amount of analog circuitry in devices is increasing as more functionality ...
DRAM for energy- and area-efficient analog in-memory computing
Oct 9, 2023 · When implemented in an energy-efficient way, this in-memory computing reduces the dependence of the inference on the cloud, largely improving latency and energy consumption. A generic architecture for analog in-memory computing. Unlike traditional memory operations, in-memory computation does not happen at the granularity of a single memory ...
