Single ended output amplifier circuit

The fact is rather difficult to digest: vacuum tube amplifiers are more efficient in producing high fidelity music output compared to the transistorized or even some of the modern linear IC amplifiers. Especially when it comes to the processing of high input frequencies, modern equipment tends to get a bit twitchy. Comparatively, vacuum tube amplifiers are much cleaner when dealing with high frequencies, and mind you, a music signal is always full of them. People who have used vacuum tube audio amplifiers greatly appreciate their outstanding performance, perhaps because of the sound quality still lingering in their ears. In this article we discuss how we can build, instead of buying, a simple single-ended tube amplifier.

A Low Power, Low Cost, Differential Input to a Single-Ended Output Amplifier

One of the most common questions asked is the difference between single-ended and differential signals inputs, and what applications they should be considered in. This allows the measurement of the voltage difference between two signals tied to the same ground and provides superior common-mode noise rejection.

Where should differential signal inputs be used? The effect on a single-ended input is usually a voltage fluctuation between signal high and signal ground. A single signals input has no commond mode range because there is only ONE low wire, which is shared by all inputs. Some cards may have several LOW lines to provide extra places to make your ground connection, however, these lines are tied together and are basically the same thing.

Differential inputs provide a more stable reading when EMI or RFI is present, and therefore, it is recommended to use them whenever noise is generally a problem. This is especially true when measuring thermocouple, strain gage and bridge type pressure sensor inputs, since they produce very small signals that are very succeptible to noise.

Electrical Engineering Stack Exchange is a question and answer site for electronics and electrical engineering professionals, students, and enthusiasts. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search. I'm designing probably over-designing, but I want the experience a four-input, four-output, stereo mixing setup for my PC setup, but I'm concerned that just tying all the ground lines from that many inputs is going to cause ground loops and similar issues. The inputs are going to come from my PC, an FM radio board, and other headphone-jack style input sources, while the outputs are going to go to my PC speakers, a pair of headphones, the line-in jack on the PC, and a spare auxiliary output.

Gain bandwidth issue of fully differential amplifier

A differential amplifier is a type of electronic amplifier that amplifies the difference between two input voltages but suppresses any voltage common to the two inputs. Single amplifiers are usually implemented by either adding the appropriate feedback resistors to a standard op-amp , or with a dedicated integrated circuit containing internal feedback resistors. It is also a common sub-component of larger integrated circuits handling analog signals. In practice, however, the gain is not quite equal for the two inputs. A more realistic expression for the output of a differential amplifier thus includes a second term:. As differential amplifiers are often used to null out noise or bias voltages that appear at both inputs, a low common-mode gain is usually desired.

Operational Amplifiers

The continuing story of input drivers brings us to the case where your signal source is single-ended, but your ADC accepts a differential input. What's the solution? The Single-Ended to Differential Driver is your ticket to ride. By mirroring the gains and choosing the right offset, you can properly feed your ADC's differential input! So let's take two of these circuits and generate two outputs of opposite polarity.

Why Buy a Single Ended Tube Amplifier When You can Build One?

How do I make a low cost, low power, differential input into a single-ended output amplifier? In many applications, there are requirements of low power, high performance differential amplifiers to convert small differential signals to a readable ground referenced output signal. Input voltages at two inputs usually share a large common-mode voltage. The differential amplifier rejects the common-mode voltage and the remaining voltage is amplified and presented on the amplifier output as single-ended voltage.

Single-Ended Input Differential Output Amplifier

Differential amplifiers are used mainly to suppress noise. Noise consists of typical differential noise and common-mode noise, of which the latter can easily be suppressed with an op-amp. There are two main causes of common-mode noise:. In either case, the ground potential, a reference for a circuit, fluctuates because of noise. It is difficult to remove common-mode noise with typical filters.

The operational amplifier or OP-AMP is a direct coupled, high gain amplifier used to perform a wide variety of mathematical operation used to perform like summation, subtraction, multiplication, differentiation and integration etc. In analog computers it is often referred to as the basic linear or analog integrated circuit IC. The operational amplifier works in different modes depending on the nature of its job. These modes are explained below. In Figure a input signal is applied to terminal 1 and terminal 2 is ground. Figure shows that an amplified and inverted output signal is obtained at V01 but an equally amplified and in phase signal appears at V02 which is terminal 4. When input signal Vin2 is applied to input terminal 2, an amplified and inverted signal appears at output terminal 4 whereas equally amplified but in phase signal appears at terminal 3 this is shown in Figure b.

1.6: The Differential Amplifier

An operational amplifier op-amp is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. Operational amplifiers had their origins in analog computers , where they were used to do mathematical operations in many linear, non-linear and frequency-dependent circuits. Characteristics of a circuit using an op-amp are set by external components with little dependence on temperature changes or manufacturing variations in the op-amp itself, which makes op-amps popular building blocks for circuit design. Op-amps are among the most widely used electronic devices today, being used in a vast array of consumer, industrial, and scientific devices.
