摘要： A broadband high output current output stage includes at least one first differential pair for enhancing the bandwidth. A second differential pair is further disposed in the circuit. The second differential pair is coupled to one of the first differential pair, such that a large output voltage swing is distributed to all transistors to avoid breakdowns thereof. A feedback unit is connected between each bias unit and the first differential pair. The first compensation unit compensates the electric characteristic of the high-frequency zero of the feedback unit and the bias unit, thereby broadening the linear bandwidth of the frequency response. The second compensation units are disposed between the first differential pairs. Each second compensation unit compensates the high-frequency zero of the node where each two first differential pairs are cascaded, thereby further broadening the linear bandwidth of the frequency response.

摘要： Constant and accurate signal gain systems based on controlling oscillator loop gain. A constant gain positive feedback network and an amplifier form an oscillator. Only when the oscillator loop gain is at least one does the oscillator produces an AC signal. Negative feedback of the oscillator's AC signal level is used to keep the loop gain close to or at the value of one by controlling the loop gain of the oscillator circuit. By maintaining the loop gain of the oscillator circuit substantially constant the signal gain is also maintained substantially constant.

摘要： A negative-feedback type ultra-wideband signal amplification circuit is proposed, which is designed for integration to an ultra-wideband (UWB) signal processing circuit system for providing a low-noise amplification function to UWB signals. The proposed circuit architecture is characterized by the provision of a dual-step filter circuit on the input side, the provision of a resistive-type feedback circuit in the transistor-based amplification circuitry, and the provision of a common-source transistor-based amplification circuit on the output side. These features allow the proposed signal amplification circuit to have flat power gain, lower power consumption, low noise figure, and higher operational stability.
