The caller identification and answering machine are advanced telephone functions. The telephone system can be used as a tele-security system. This research work is based on the potential use of a low cost 8-bit microcontroller. The caller identification (caller ID) system is a feature of digital telephone networks and is supported by signaling system no. 7 (SS7) which uses a separate call data circuit. The caller ID information is transmitted on the subscriber loop using frequency shift key (FSK) modem tones and data is embedded between the first and second ring of the ringing signal. A caller ID decoding circuit has been designed for decoding the FSK modem tone and the appropriate ASCII code is displayed in the LCD unit. An answering machine is a device that answers the telephone calls in the absence of the called party and records the incoming message into a cassette. A ring detector circuit, outgoing message (OGM) sender circuit, tape driver circuit, dual tone multiplexed frequency (DTMF) encoder circuit and calling party control (CPC) circuit have been developed for the answering machine device. The DTMF generator circuit and sensor signal management circuit have been integrated to provide a tele-security system. A PIC 16C84 (8-bit microcontroller) controls all logic operations as it was programmed. Software has been produced in assembly language for programming of the microcontroller.","PeriodicalId":356206,"journal":{"name":"ICSE'98. 1998 IEEE International Conference on Semiconductor Electronics.

P-I-N diode, bipolar transistor and MOSFET models have been applied to gain physical insight into the structure. A design approach has been formulated for blocking voltage capability, forward current density, forward voltage drop and latching current density, which is crucial to device operation. Based on this approach, a 1000 V, 20 A n-channel vertical IGBT has been designed. Various structural parameters such as W, L/sub n//sup +/, L/sub C/, L/sub CH/ and process parameters X/sub j/, /spl rho//spl square/, t/sub ox/, t/sub poly/, impurity concentration, etc. have been computed. Trade-offs curves for J/sub c/-V/sub a/, V/sub F/-d/L/sub a/, J/sub CL/-L/sub n//sup +/, L/sub CL/-C/sub BS/ have been obtained from design and simulation. The calculated values of various design parameters are N/sub d/=2.35/spl times/10/sup 14/ atoms/cm/sup 3/, W=100 /spl mu/m, p-base surface concentration=1/spl times/10/sup 17/ atoms/cm/sup 3/, p-base depth=4 /spl mu/m, L/sub n//sup +/=6 /spl mu/m, n/sup +/ depth=1 /spl mu/m, L/sub CH/=2 /spl mu/m and t/sub ox/=9000 /spl Aring/, with poly-Si gate. Unit cell size is 40 /spl mu/m/spl times/40 /spl mu/m. The results presented provide guidelines for designing high-voltage and high-current bipolar transistors for various applications.","PeriodicalId":356206,"journal":{"name":"ICSE'98. 1998 IEEE International Conference on Semiconductor Electronics.
