How to specify and use analog switches
An analog switch is an IC that can be used to control connections to analog and digital signals. These switches provide bidirectional connections when "on" and high impedance paths when "off." There’s … [Read More...] about How to specify and use analog switches
How do comparators and op amps compare?
Operational amplifiers (op amps) and comparators have two inputs, inverting and noninverting, and an output that can usually swing from rail to rail and have the same schematic symbol. So, what’s the … [Read More...] about How do comparators and op amps compare?
Analog subsystem simplifies integration of multiple analog IPs into ASICs
Agile Analog has launched its first range of analog subsystems, covering power management, PVT sensing, and sleep management. These innovative, digitally wrapped subsystems significantly reduce the … [Read More...] about Analog subsystem simplifies integration of multiple analog IPs into ASICs
How to specify and use voltage references
Voltage references are small components that can have a significant impact, either positive or negative, on system performance. They are precision devices that maintain a constant voltage output even … [Read More...] about How to specify and use voltage references
When reality intrudes on component models and equivalent circuits
Determining the utility of an equivalent-circuit model versus construction reality is often a difficult challenge. Using simplified, first-order approximations in models and equivalent circuits is … [Read More...] about When reality intrudes on component models and equivalent circuits

New common-mode filters from STMicroelectronics have an extremely wide differential bandwidth of 10.7GHz to protect antenna sensitivity in adjacent wireless circuitry from the latest serial digital … [Read More...] about Common-mode filters boast 10.7 GHz bandwidth
What’s the difference between equalizers?
Equalizers are used to alter the performance of signal chains. In some cases, that means linearizing signal chain performance. In other cases, equalizers are used to introduce nonlinearities. As a … [Read More...] about What’s the difference between equalizers?
What do you do with a bucket brigade device?
A bucket brigade device (BBD) is a discrete-time analog delay line using capacitors that has been replaced in most digital signal processing applications. But it continues to be used in some specialty … [Read More...] about What do you do with a bucket brigade device?
What’s a logarithmic resistor ladder good for?
A logarithmic resistor ladder consists of a resistor string and switches designed to attenuate a signal. The state of the switches can be considered to represent a digital code proportional to the … [Read More...] about What’s a logarithmic resistor ladder good for?
What causes noise in analog designs and how can it be controlled?
Controlling noise in analog and mixed-signal circuits is important but not simple. Data integrity is dependent on controlling noise in the signal chain. If left uncontrolled, noise can impair or … [Read More...] about What causes noise in analog designs and how can it be controlled?
Five considerations for mixed-signal PCB layouts
