|Non-binary decoder architecture and control signal logic for reduced circuit complexity|
A decoder for sequentially enabling outputs in response to clock signal inputs is described including x number of logic stages corresponding to x number of outputs of the decoder. Each of the logic stages has a plurality of inputs, wherein each logic stage includes fewer than log2x inputs for receiving the clock signal inputs..
|Load driving device and system, limiting point control method and device|
A load driving device and system, and a limiting point control method and device. The load driving device comprising: a voltage/current regulative main circuit placed under the control of an output current controller, for use in conducting a voltage conversion on an input voltage, and in supplying electric power to a subsequent load unit; a sampling unit connected to an output terminal of the main circuit, for use in sampling an output feature parameter of the main circuit; the output current controller, for use in controlling a limiting point of the main circuit, and on the basis of the adjustment direction of the limiting point and on changes of the output feature parameters of the main circuit before and after an adjustment, determining a steady working point for the main circuit, and controlling the main circuit to work at the steady working point.
|Anti-blooming circuit for integrating photodiode pre-amplifiers|
An input clamping circuit of a photo detector preamplifier is activated when an input transistor is turned off by an input overload, and the drain voltage of the input transistor is pulled toward ground by a current source. Even with extreme overloads, the operating conditions (vgs and id) of the input transistor remain within normal range.
|Vertical 4-way shared pixel in a single column with internal reset and no row select|
A method and apparatus for reducing space and pixel circuit complexity by using a 4-way shared vertically aligned pixels in a same column. The at least four pixels in the pixel circuit share a reset transistor and a source follower transistor, can have a plurality of same colored pixels and a plurality of colors, but do not include a row select transistor..
|Mixer circuit and variation suppressing method|
In a mixer circuit that solves the problem of the extreme increase in circuit complexity that accompanies compensating for amplitude errors and phase errors, a voltage current conversion unit (11) converts an rf signal, which is a voltage signal, to a current signal and supplies the current signal. An rf path selection unit (12) connects its input terminal to any of its output terminals in accordance with the state of a four-phase clock signal and separately supplies, from its output terminals, a plurality of if signals obtained by multiplying the rf signal by clock signals in the four-phase clock signal.
|Green power converter|
The invention discloses a green power converter which omits the pulse width modulation (pwm) technique in the traditional power converter, does not have high-frequency power device, does not generate emi interference, simultaneously adopts the symmetry basic primitive (sbp) technique, the amplitude high modulate (ahm) technique and the dynamic rectification (dr) technique, and only needs to perform traditional power conversion on a small part of the input power so as to acquire the whole output power, namely that a large part of the output power neither need traditional power conversion nor need to pass through a magnetic core transformer. The input ac voltage neither needs to be rectified and filtered nor has large inductance and large capacitance, thus the power factor is 1, and the total harmonic distortion (thd) is 0.
