Abstract:The paper discusses possibilities of current-mode based functional block implementation into signal path of HV SoI voltage-mode circuits. The topic arose as an effect of research on HV SoI ASICs for automotive applications. It turned out, that simplicity, consistent structure and ease of HV application of current-mode processing, make it better suited for some application areas, then typical voltage-mode of signal processing. It is shown in the paper that a special set of HV/I and I/HV converters can work as an envelope for current-mode functionality inside HV voltage-mode signal paths. Due to required precision and high input/output impedance, special voltage buffer structure devised by author is applied here. The paper discusses and presents potential of quite different current-mode HV functional blocks. Among others there are: an HV voltage inverter – a simple alternative to a quite challenging HV fully-differential OPAMP, and a voltage trapezoidal waveform generator. The latter works using one input LV digital signal for coding the waveform and set of current signals for precise operation control. In total several function blocks and their simulations are discussed to present potential of current-mode signal processing block implementation in HV integrated circuits.
