Temperature-to-period circuit provides linearization of thermistor response

Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors' resistance-versus-temperature characteristics are highly nonlinear and need correction for applications that require a linear response. Using a thermistor as a sensor, the simple circuit in Figure 1 provides a time period var ...

Building A Quadcopter For Newbie

Drones are one of the rising technologies in the world and it became very popular that we see it in news on places that have armed conflicts, aerial photography like GoPro drones and even for customer care like the Prime Air delivery system from Amazon which is designed to get packages to customers using small unmanned aerial vehicles (aka drones). As the name implies, the quadcopter has four propellers and ...

Introduction to I²C and SPI protocols

I²C vs SPI Today, at the low end of the communication protocols, we find I²C (for ‘Inter-Integrated Circuit’, protocol) and SPI (for ‘Serial Peripheral Interface’). Both protocols are well-suited for communications between integrated circuits, for slow communication with on-board peripherals. At the roots of these two popular protocols we find two major companies – Philips for I²C and Motorola for SPI – and ...

Benefits of Using A Buck-Boost Converter As A Pre-regulator For LDOs

Intersil published a new white paper titled “Preventing Subsystem Brownouts in Mobile Devices“. This white paper demonstrates the benefit of using a buck-boost converter as a pre-regulator, which leads to better overall system efficiency and enhanced battery life. Systems powered from a battery may have voltage brownout when they are subjected to a burst current discharge, that is because of internal resist ...

Adding ADC to Microcontrollers without ADC

I recently had the need to carefully measure a voltage with a microcontroller which lacks an analog-to-digital converter (ADC), and I hacked together a quick and dirty method to do just this using a comparator, two transistors, and a few passives. The purpose of this project is to make a crystal oven controller at absolute minimal cost with minimal complexity. Absolute voltage accuracy is not of high concer ...

Analog front-end IC linearizes sensors

A 10-channel temperature-measurement IC, the LTC2986 from Linear Technology directly digitizes any combination of thermocouples, RTDs, thermistors, and external diodes with 0.1°C accuracy and 0.001°C resolution. The analog front-end device combines three 24-bit delta-sigma ADCs with all the necessary excitation and control circuits for each sensor. On-chip EEPROM stores user configuration data and custom se ...
