摘要： An analog variable gain amplifier (VGA) adjusting a signal level of a mobile communication system is provided. More particularly, design of a VGA using an operational transconductance amplifier (OTA) having a wide linear input/output range is disclosed. The VGA includes two double-differential-pair OTAs and feedback resistors. A first differential input of a first double differential pair OTA receives an input signal from the forward stage, and a second differential input is negatively fed back through a differential output and a passive resistor. An input in which a first block of the connection structure and first and second differential inputs of a second double differential pair OTA are connected receives an output signal of the first block stage. The output is negatively fed back in series through a variable resistor whose resistance varies exponentially with an adjustment voltage from outside. According to the VGA, it is possible to provide a characteristic of linear variation of gain on a logarithmic scale with respect to a control voltage with a simple and inexpensive constitution. In addition, the VGA can be designed for a low pass filter having a conventional OTA used for a core circuit, and has a simple circuit structure. Therefore, the VGA is convenient for high integration and low-power design, and thus is appropriate for a terminal chip and so forth.

摘要： A feedback-type variable gain amplifier including a first field effect transistor, a feedback circuit, and a load circuit. The first field effect transistor receives an input voltage signal through an input node, amplifies the input voltage signal, and outputs the amplified input voltage signal through an output node. The feedback circuit is coupled between the input node and the output node, and generates feedback impedance that is changed in response to a control signal. The load circuit is coupled between the output node and a voltage source, and generates load impedance that is changed in response to the control signal to cancel a change of input impedance due to a change of the feedback impedance. Therefore, since the input impedance is not changed when the gain of the amplifier is changed, a voltage standing wave ratio is good, and a range of gain control is broad.
摘要翻译：一种反馈型可变增益放大器，包括第一场效应晶体管，反馈电路和负载电路。第一场效应晶体管通过输入节点接收输入电压信号，放大输入电压信号，并通过输出节点输出放大的输入电压信号。反馈电路耦合在输入节点和输出节点之间，并产生响应于控制信号而改变的反馈阻抗。负载电路耦合在输出节点和电压源之间，并且产生响应于控制信号而改变的负载阻抗，以抵消由于反馈阻抗的变化引起的输入阻抗的变化。因此，由于当放大器的增益改变时输入阻抗不变，所以电压驻波比良好，增益控制范围宽。

摘要： An amplifier-based system having pulsed output includes an amplifier for amplifying a time varying voltage signal to produce an output voltage signal. A voltage-to-current (V-I) converter converts the output voltage signal into a current signal. An output stage including a current integrator integrates the current signal to generate an integrated voltage. An amplitude to time converter generates a pulse train from the integrated voltage, wherein a timing of the pulses in the pulse train represents the original time varying voltage signal. The pulse train representation permits transmission and accurate remote reconstruction of the original time varying voltage signal, such as signals generated by electrodes implanted inside a subject, including neural signals.
