This paper presents an eight-channel inverter transimpedance amplifier (INV-TIA) array realized in a standard 0.18 ㎛ CMOS technology for the applications of linear laser detection and ranging (LADAR) systems. For comparison purposes, a couple of multi-channel TIA arrays including a four-channel current-mirror transimpedance amplifier (CM-TIA) array, and a four-channel INV-TIA array are demonstrated together.
A typical linear LADAR system mandates a compact high-speed read-out integrated circuit (ROIC) to capture the reflected lights from a target. Therefore, the design approach of a conventional current-mode TIA is an easier way. However, the crosstalk performace between channels of the current-mode TIAs gets seriously detrimental in accordance with increasing frequencies. Hence, we exploit a voltage-mode INV-TIA array in this work so as to lower the crosstalk between channels for comparable gain, bandwidth, and power consumption characterstics.
