An increase in amount or degree: 增加:总额或程度的增加: 例句: a gain in operating income. 营业收入增加 ElectronicsAn increase in signal power, voltage, or current by an amplifier, expressed as the ratio of output to input.Also calledamplification ...
The amplification factor, also called gain , is the extent to which an analog amplifier boosts the strength of a signal . Amplification factors are usually expressed in terms of power . The decibel (dB), a logarithmic unit, is the most common way of quantifying the gain of an amplifier. F...
12. profit or advantage: I see no gain in this plan. 13. an increase or advance: a gain in weight; a gain in power. 14. gains, profits or winnings. 15. the act of gaining; acquisition. 16. a. a measure of the increase in signal amplitude produced by an amplifier, expressed...
: an increase in amount, magnitude, or degree a gain in efficiency b : the increase (as of voltage or signal intensity) caused by an amplifier especially : the ratio of output over input c : the signal-gathering ability of an antenna gain...

The Inverting Programmable Gain Amplifier (PGA_Inv) component implements an opamp-based inverting amplifier with user-programmable gain. It is derived from the switched capacitor/continuous time (SC/CT) block. The inverting gain can be between -1.0 (0 dB) and -49.0 (+...
Amplification factors are usually expressed in terms of power . The decibel (dB), a logarithmic unit, is the most common way of quantifying the gain of an amplifier. For power, If the output-to-input signal power ratio is 1:1, then the amplification factor is 0 dB. ...
An improved version of the gain switched amplifier sensitive to large input dynamic range is described. While the accuracy of the logarithmic amplifier is limited, in the already developed gain switched amplifier, the switching pulses come along with the main output which cause problems in the ...
The circuit configuration is that of an inverting amplifier, with R2 replaced by the effective resistance of the DAC ladder (Figure 1) and R1 replaced by internal feedback resistor RFB (Figure 2). In this circuit, an AC signal is applied to the feedback resistor input and the output signal...
However, micro- and ultra-low-power instrumentation amplifiers are used in wearable devices. An example of a low-power instrumentation amplifier is AD621 by Analog Devices, for which the power supply current is in the order of tens of μA. Commonly, in practical applications, R4 is not ...
