Analog Electronics deals with electronic systems that has a continuous variable signal. In this section we will discuss about various analog electronic projects that can be used to design your own amplifiers, oscillators, filters, analog converters, waveform generators and other analog circuits as required by your application.
Sensors are an integral part of any measurement system as they help in converting the real world parameters into electronic signals that could be understood by machines. In an industrial environment, the commonly used type of sensors is the Analog Sensor and Digital sensors. Digital sensors communicates with 0’s and 1’s following protocols like USART, I2C, SPI etc. And…
Mouser Electronics is now stocking the OPA855 decompensated amplifier from Texas Instruments (TI). Designed as a wideband, low-noise, bipolar-input operational amplifier, the OPA855 excels in high bandwidth transimpedance and voltage amplifier applications. The 8-GHz gain-bandwidth product (GBWP) of the OPA855 enables high-gain configurations while maintaining wide closed-…
Texas Instruments released new small sized current-sense amplifier in a leaded package and small, accurate comparators with an internal 1.2V or 0.2V reference. The new INA185 current-sense amplifier, and open-drain TLV4021 and push-pull TLV4041 comparators help engineers to design smaller, simpler and more integrated systems while maintaining high performance. The amplifiers…
There are various resonators that are used for an immense number of applications in the field of Electronics. In those list of resonators, the two mainly used materials are quartz crystal and Ceramic (making Ceramic Resonator). Quartz crystal is used in Crystal Oscillator and Ceramic is used in Ceramic Resonator. Both of them have the same aim of generating an oscillation…
Just like situations in which we need to regulate the voltage in our designs, there are scenarios where we need to regulate the current that’s being supplied to a particular part of our circuit. Unlike transforming (changing from one voltage level to another), which is usually one of the major reasons for voltage regulation, current regulation is usually about keeping the…
In the previous article, we discussed about Current Mirror Circuit and how it can be built using a Transistor and a MOSFET. Even though a basic current mirror circuit can be constructed using two simple active components, BJTs and MOSFETs or using an amplifier circuit, the output is not perfect, as well as it has certain limitations and dependencies on the external factors.…
When an RC phase shift oscillator employs an op-amp in its circuit, it becomes an electronic oscillator with a stable sine wave output. It functions by developing two groups of 180-degree phase shifts, one via the RC network and the other via an op-amp in an inverting circuit. Due to this phase shift arrangement, it produces nearly pure sinusoidal signals with extreme frequency stability and…
The term Supercapacitors and its possible usage in Electric Vehicles, Smartphone’s and IoT devices are being considered extensively in the recent times, but the idea of super capacitor itself dates back to 1957 when it was first experimented by General Electric to increase the storage capacity of its capacitors. Over the years Super capacitor technology has improved…
The Current Mirror is a widely popular technique for monolithic IC design. In this technique, the circuit is designed in such a way that it copies the current through one active device to another active device with current control feature. In this, the current is flowing through one device can be copied into another device but in inverting form. If the current of the first…
Sziklai Transistor Pair was first designed by George Sziklai to overcome some efficiency related issues with Darlington pair, which will be discussed later in this article. It is also known as compound or pseudo-Darlington pair. This transistor pair consists of two bipolar transistor pairs, where one is NPN and another is PNP. The Sziklai pair looks similar to the Darlington…
The situation is simple – you have a low voltage supply rail, say 3.3V, and you want to power something that needs 5V. This is a tough call, especially if batteries are involved. The only apparent way is a switch mode converter, more specifically a boost converter.
This is where we hit a roadblock – boost converters are inefficient at low powers,…
The Wireless Electricity Transfer concept is not new. It was first demonstrated by Nikola Tesla in the year 1890. Nikola Tesla introduced electrodynamics induction or resonant inductive coupling by lighting up three light bulbs from the distance of 60 feet from the power source. We have also built a Mini Tesla Coil to transfer the energy.
Wireless…
