Current-mode signal processing implementation in HV SoI integrated systems
The paper presents and discusses possibilities and potential of current-mode based signal processing in high-voltage (HV) integrated systems, including current-mode functional block implementation into signal path of HV voltage-mode circuits. The paper is mostly focused on analog circuitry, implemented with the use of SoI processes. Discussion is based on the range of circuit solutions previously devised by authors and presently combined to present cumulated potential of current-mode approach in high-voltage (HV) integrated circuits. Analysis of the referenced research conducted by the authors of the paper, points out that in HV integrated systems, there are application areas well suited for current-mode processing implementation rather than the classic voltage-mode approach. Simplicity and consistency of HV current-mode functional blocks are presented, along with fitness of current-mode circuits for convenient implementation into HV SoI integrated circuits, with very limited loss of operation quality as compared to corresponding low-voltage functional blocks. Means of implementing current-mode circuits into HV voltage-mode systems are discussed.
