When driving the differential inputs with an amplifier, the actual common mode range is determined by the output swing of the amplifier. If the differential inputs are not driven from an amplifier, the common-mode range is determined by the supply voltage on the VDD supply pin and the VSS ...

Large source impedances significantly affect the ac performance of the ADC and can necessitate the use of an input buffer amplifier. When no amplifier is used to drive the analog input, the source impedance should be limited to low values. The maximum source impedance depends on the amount of...
Still referring to FIG. 1, the time-varying current signal output from the detector 60 is applied to a pre-amplifier and detector area select circuit 90. As its name implies, the circuit 90 provides initial gain to the current signal from the detector 60, and is used in the selection of...

FIG. 6c further simplifies this signal model by combining amplifiers 62, 63 into amplifier 63′, with a gain of 2b; amplifier 63 is then eliminated. As such, the delta impulse is multiplied by a factor of 2b, and integrated twice, before being spectrally “flipped” by multiplier 61 and ...

The acoustic transducer 80 may include a microphone, a low-pass filter, a gain amplifier, and a threshold comparator. The acoustic transducer 80 may include an omnidirectional microphone, although any other suitable acoustic transducer device would suffice. The microphone may be a surface mount MEMS...
Within the present state of the technology, for numerous BRA Transceiver applications, it is not practical to introduce band-pass filtering after the NLA power efficient Radio Frequency (RF) final amplifier stage. Here we are using the term “Radio Frequency” (RF) in its broadest sense, implyi...
