The sensitivity of an electronic device, such as a communications system receiver, or detection device, such as a PIN diode, is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria. In general, it is the signal level required for a particular ...
In most amplifiers a reduction in gain takes place before hard clipping occurs; the result is a compression effect, which (if the amplifier is an audio amplifier) sounds much less unpleasant to the ear. For these amplifiers, the 1 dB compression point is defined as the input power (or output power) where the gain is 1 dB less than the small ...
Receiver sensitivity: 0.25 μV at 12 dB SINAD. This is stating that the receiver will produce intelligible speech with a signal at its input as low as 0.25 μV. Radio receiver designers will test the product in a laboratory using a procedure, which is typically as follows:
Audio level at a listener's ears depends on the listening environment, listener position, speaker sensitivity as well as amplifier gain. For loudness compensation to work correctly the playback system must also accurately assume what volume level was used in mastering .
The current-feedback operational amplifier (CFOA or CFA) is a type of electronic amplifier whose inverting input is sensitive to current, rather than to voltage as in a conventional voltage-feedback operational amplifier (VFA). The CFA was invented by David Nelson at Comlinear Corporation, and first sold in 1982 as a hybrid amplifier, the CLC103.
A negative-feedback amplifier (or feedback amplifier) is an electronic amplifier that subtracts a fraction of its output from its input, so that negative feedback opposes the original signal. [1] The applied negative feedback can improve its performance (gain stability, linearity, frequency response, step response ) and reduces sensitivity to ...
NAD 3020 integrated amplifier. The NAD 3020 is a stereo integrated amplifier by NAD Electronics, considered to be one of the most important components in the history of high fidelity audio. [1] Launched in 1978, this highly affordable product delivered a good quality sound, which acquired a reputation as an audiophile amplifier of exceptional ...
Their input stages are designed such that when the input common-mode voltage is much higher than V CC or much lower than V EE, the input amplifier stage powers itself from the input common-mode voltage instead of V CC orV EE. [2] Examples of integrated current-sense amplifiers include INA240, INA293, LTC6101,MAX4080, AD8210,TS1100 and INA193.
