摘要： There is disclosed a microchip reactor capable of being used in research on reaction kinetics. With this microchip reactor, the time (reaction time) elapsed until a measurement is made since mixing of two liquids is variable. The microchip reactor comprises a base portion and a movable portion which have sliding contact surfaces that are in contact with each other. The base portion and movable portion have their respective downstream flow channel portions which meet at an intersection. Different reagents are introduced at the intersection, mixed, and reacted. An opening is formed in the movable portion. A slot is formed in the base portion. The major axis of the slot is in the direction of sliding motion of the movable portion. The position of the intersection where the reagents are mixed is determined by the intersection of the opening and the slot.

摘要： Bias current generation circuits and systems are disclosed. In one embodiment, a gain boosting cascode system comprises a cascode based on a transconductance amplifier and a current buffer and a gain booster circuit coupled to the cascode optimally boosting a gain of the cascode by maintaining the transconductance amplifier and the current buffer in their respective saturation regions. The gain booster circuit is based on one or more feedback amplifiers coupled in series with a main voltage control transistor. The main voltage control transistor is maintained in a triode region, and the voltage at the drain of the main voltage control transistor can be set by passing an appropriate amount of current through the main voltage control transistor. This in turn would keep the transconductance amplifier and the current buffer in their respective saturation regions, thus generating the optimal gain for the gain boosted cascode system.

摘要： A current processing circuit having reduced charge and discharge time constant errors caused by variations in operating temperature and voltage while conveying charge and discharge currents to and from a capacitor, respectively. Instead of switching both the charge and discharge currents on and off, only the charge current is switched. The discharge current, generated and sunk by a current mirror circuit, remains on at all times. The charge current is two times the nominal discharge current. The actual discharge current is the sum of the nominal, or desired, discharge current, plus a small error current component introduced by the current mirror circuit generating the discharge current (thereby making the charge current approximately two times the actual discharge current). Alternatively, the discharge current can be switched while the charge current, generated and sourced by a current mirror circuit, remains on at all times. The discharge current is two times the nominal charge current. The actual charge current is the sum of the nominal, or desired, charge current, plus a small error current component introduced by the current mirror circuit generating the charge current (thereby making the discharge current approximately two times the actual charge current). As a result, the charging and discharging time constants of the capacitor are significantly less dependent upon operating temperature and voltage.

摘要： An attenuating antenna switch may be used to suppress increase in the scale and power consumption of an RFIC. The antenna switch has a first terminal, a second terminal, and an antenna terminal coupled to the first and second terminals and configured to be connected to an antenna. The first switch switches between a first state in which a high frequency signal is propagated between the first terminal and the antenna terminal, and a second state in which the high frequency signal is interrupted. A second switch switches between the first and second states between the second terminal and the antenna terminal. The first and second switches are controlled in a mutually exclusive manner such that only one of the two switches can be in the first state at any given time. When in the first state, each switch adjusts an attenuation amount of the high frequency signal.
