Abstract: The present invention provides an exhaust heat recovery device configured to perform heat exchange between three media such as, exhaust gas, coolant, and oil. According to preferred embodiments of the present invention, the exhaust heat recovery device is configured such that the heat of exhaust gas discharged from an engine is transmitted to the coolant and the oil at the same time and direct heat exchange between the coolant and the oil is made, thereby simultaneously increasing the temperature of the coolant and the oil during the initial start-up of the engine (fast warm-up). As a result, it is possible to reduce friction loss of powertrain, thereby improving fuel efficiency. Accordingly, an object of the present invention is to provide an exhaust heat recovery device which is configured to perform the integral heat exchange between the exhaust gas, the coolant, and the oil.

Abstract: An analog baseband circuit includes first and second DC (direct current) offset cancellers and an offset canceller controller. The first DC offset canceller includes a first filter and a first PGA (programmable gain amplifier) with a first gain step for eliminating a first dc component from an input baseband signal. The second DC offset canceller includes a second filter and a second PGA with a second gain step less than the first gain step for eliminating a second dc component from an output of the first DC offset canceller. The offset canceller controller controls the first and second filters to operate in a fast mode when a gain of the first PGA is changed.

Abstract: A capacitance multiplier includes a self-biasing active load for generating a stable bias voltage without a separate current bias. In addition, the capacitance multiplier includes a cascode load within a multiplying section for increasing the output resistance and in turn the charging/discharging efficiency. Furthermore, the capacitance multiplier is implemented with a plurality of multiplying paths to reduce effects of noise for more stable generation of the multiplied capacitance.
