In one embodiment, a bipolar cell () includes a cell boundary () that defines a cell active area (), a first array of bipolar transistors () is formed within the cell active area () and configured for a first function. The bipolar transistors () within the first array () are parallel to each other. The bipolar cell () further includes a second array of bipolar transistors () formed within the cell active area () and configured for a second function that is different than the first function. The bipolar transistors () within the second array () are parallel to each other and oriented in a different direction than the transistors () in the first array ().

Cell structure for bipolar integrated circuits and method

A transceiver (10) has a transmitter (12) and an image reject receiver (16). The image reject receiver (16) provides frequency translation of two modulated signals received from an antenna (14). The image reject receiver (16) has two mixers (22 and 32) to accomplish the frequency translation. One mixer (22) receives a modulated signal for GSM operation and the other mixer (32) receives a modulated signal for DCS/PCS operation. A local oscillator (24) generates another signal having a gain controlled by an amplifier (26) for supplying differential signals to both of the mixers (22 and 32). The amplifier (26) uses transistors (46 and 58) with inductors (40, 52, and 68) to generate the differential signals.
