摘要： The thermal interference due to the self heating of transistors constituting a gilbert cell circuit is reduced, thereby largely improving the receiving sensitivity to signals. A mixer circuit composed of a gilbert cell circuit comprises transistors T1 to T6. Each of the transistors T1 to T4 is con figured so that four transistors may be connected in parallel. In a layout on a semiconductor chip, four transistors T1a to T1d and T2a to T2d respectively constituting the transistors T1 and T2 are respectively separated into two pairs, and the respective two pairs are laid out in a crisscross shape so that they are crossed with each other. Similarly, four transistors T3a to T3d and T4a to T4d respectively constituting the transistors T3 and T4 are respectively separated into two pairs, and the respective two pairs are laid out in a crisscross shape so that they are crossed with each other. Thus, the thermal influence applied on the transistors T1 to T4 is uniformed.

摘要： A receiving circuit of a direct conversion system is provided which includes a differential amplifier circuit which amplifies a received signal, a mixer which combines the amplified received signal and an oscillation signal having a predetermined frequency to thereby perform frequency conversion, and a high gain amplifier circuit in which a plurality of programmable gain amplifiers and a plurality of filters which eliminate noise of the received signal and an unnecessary wave, are connected in a multistage and which is configured such that an amplification factor is varied according to the level of the received signal. In the receiving circuit, the low noise amplifier is brought to a non-operating state to thereby allow execution of a DC offset cancel operation of the corresponding programmable gain amplifier on the pre-stage side of the high gain amplifier circuit. Thereafter, the low noise amplifier is brought to an operating state to thereby allow execution of a DC offset cancel operation of the final-stage programmable gain amplifier.

摘要： The semiconductor device provided assures stable communication processes. For example, a varactor diode for adjusting the reference frequency is comprised within a digital crystal-controlled oscillating circuit provided as an internal circuit of the front-end circuit for generating the reference oscillation signal of a PLL circuit or the like. The varactor diode is formed to a semiconductor layer DF of the so-called SOI structure in the structure where an embedded insulating layer, a n−type semiconductor region, a p type semiconductor region, and a n+ type semiconductor region are formed in this sequence and the n+ type semiconductor region is connected to a cathode node which becomes the frequency adjusting node. Moreover, a p+ type semiconductor region connected to the p type semiconductor region is formed in both sides of the n+ type semiconductor region, and this p+ type semiconductor region is connected to an anode node to which the ground voltage is applied. Accordingly, noise transferred to a frequency adjusting node via the embedded insulating layer from a semiconductor substrate can be reduced.
