Analog bootstrap circuits are traditionally ones where output is fed back to the input, usually to increase input impedance. This can be to minimize either the resistive or reactive (usually capacitive) components of the input impedance or both. The term is now also used with MOSFET drivers where a capacitor is charged and used to […]

Sigma Delta ADC vs. SAR vs. Pipeline: How to Choose
Assuming that you are familiar with the fundamental specifications of an ADC and what they mean, the next step is to know your entire signal chain well and then work to fit the ADC to the requirements. After carefully determining signal chain requirements, then select your ADC with the understanding that if the ADC is […]
Input bias current cancellation in bipolar op amps
Bipolar operational amplifiers have an essential input bias current requirement. This bias current has to come from somewhere and can be a nuisance in some types of high impedance circuits such as charge amplifiers and transimpedance amplifiers and can result in offset voltages where input resistances aren’t matched. The example shown below has an input […]
Sound design considerations for Class D amps
The first two FAQs in this series, “Class D Amplifiers for High-Efficiency Switched-Mode Sound” and “Class D Audio – Why Now?” focused on basic Class D amplifier topologies, modulation techniques, general component and technology advancements that have made Class D amplifiers an increasingly viable option, and the evolving tradeoffs between silicon and GaN power devices. […]
MIM/MOM capacitor extraction boosts analog and RF designs
Metal-insulator-metal and metal-oxide-metal capacitors popular in analog/RF designs because of their desirable characteristics. By extracting parasitics from your models that are important in your design, you’ll get a robust circuit.
Connectors facilitate 4K Ultra HD broadcast in applications requiring direct mounting
Heilind Electronics an authorized distributor for Amphenol RF, recently introduced the manufacturer’s 12G MCX connectors. The MCX line is the latest in Amphenol RF’s 12G offerings, which include high-frequency BNC and HD-BNC connectors.

Fluxgate Compasses, Part 1 – Context and principles
Despite the availability of GPS and inertial measurement units, the compass in an electronic fluxgate implementation is still a viable and needed navigational tool. The classic magnetic-needle compass is not getting much respect or attention these days. Between the Global Positioning System (GPS) and the Inertial Measurement Unit (IMU) system, the compass – whether it […]
