A METHOD AND DEVICE FOR PROCESSING SAMPLED ANALOGUE SIGNALS IN DIGITAL BiCMOS PROCESS |
摘要 |
In a digital BiCMOS process the storage capability of MOS transistors and the large transconductance of bipolar transistors can be utilized in such a way, that the speed is primarily determined by the capacitance seen by the MOS transistor (4) and the transconductance of the bipolar transistor (5). The advantages over the prior SI technique in CMOS are higher speed, smaller errors and higher accuracy. The advantages over other techniques in BiCMOS are smaller errors and higher accuracy. The unique feature of the invented technique is the combination of high input impedance of the MOS devices and high transconductance of the bipolar devices, where both devices are only available in BiCMOS process and not in the CMOS process.
