摘要： The invention relates to a high-voltage final output stage (1) for driving an electric load, of the type which comprises a complementary pair (3) of transistors connected between first (Vdd) and second (Vss) supply voltage references, and at least one PMOS pull-up transistor (MP1) connected in series with an NMOS pull-down transistor (MN). The stage (1) comprises an additional PMOS transistor (MP2) connected in parallel with the pull-up transistor (MP1) and having the body terminal in common therewith. More particularly, the body terminals of both PMOS transistors (MP1,MP2) are formed in the semiconductor within a common well which can withstand high voltages, and the additional transistor (MP2) is a thick oxide PMOS power transistor.

摘要： The circuit of a two-stage fully differential amplifier composed of a differential input stage, two output stages and a common mode feedback circuit coupled to the output nodes of the amplifier includes a non-inverting stage coupled to a respective output node of the differential input stage for driving the respective output stage. Each auxiliary non-inverting stage of the two branches of the fully differential amplifier uses as a biasing current generator, the load device of the branch of the differential input stage to the output of which the non-inverting stage is coupled. The modified circuit of the fully differential amplifier permits the use of a null-consumption common mode feedback circuit as normally employed in a single stage fully differential amplifier.

摘要： The amplifier described has an output stage constituted by an npn transistor (Q1) and a pnp transistor (Q2) in a push-pull arrangement, and a driver stage. The latter comprises a current-mirror circuit having, in its input branch, a pnp transistor (Q3) in series with a first constant-current generator (G1) and, in its output branch, an npn transistor (Q4), and two complementary transistors (Q5 and Q6) of which the collectors are connected together to the output terminal (OUT) and the bases are connected together to the input terminal (IN) of the amplifier. The emitter of the pnp transistor (Q5) of the driver stage is connected to the positive terminal (vdd) of the supply by means of a second constant-current generator (G2) and to the base of the npn transistor (Q1) of the output stage, and the emitter of the npn transistor (Q6) of the driver stage is connected to the negative terminal (gnd) of the supply by means of the npn transistor (Q4) of the output branch of the current-mirror circuit and to the base of the pnp transistor (Q2) of the output stage.
The amplifier has a very low or zero offset ( Vos = Vout-Vin ).

摘要： A power circuit (A) and an electronic device are provided. The power circuit (A) includes a power module (A1) and a power feeding module (A2) coupled to the power module (A1). The power module (A1) is configured to supply power in a time-slice power-on manner. This avoids impact of the power circuit (A) and the electronic device at a switch-on or switch-off moment on a power supply, improves stability of the power supply and reliability of the power circuit (A), reduces a size of the power circuit (A), and reduces costs of the power circuit (A).

摘要： Lightweight, physically compact and portable Guitar combined Valve Amplifier comprising: - DSP, - Power Amplifier with Dynamic Power Reduction, switchable between high (50W), low (2W) and sag -power mode; - Switched-Mode Power Supply that mimics the output impedance characteristics of a linear power supply and of valve rectifiers, including legacy rectifiers showing dynamic compression ("power supply sag"); - The high power mode provides desired legacy musical compression and distortion; - Analog filtering for the on-board dummy reactive load; - sampling of the output of the valve amplifier to provide feedback to the DSP to better model reflections and various speaker cabinets.
