Abstract
There may be provided detection circuit that may include (i) a photodiode that may be configured to convert radiation to a photodiode electrical signal; (ii) a photodiode bias circuit that may be configured to bias the photodiode, wherein the photodiode bias circuit may include a photodiode bias voltage supply and a photodiode bias capacitor; and (iii) a differential transimpedance amplifier that may be configured to amplify the photodiode electrical signal to provide a differential voltage. The differential transimpedance amplifier may include an amplification circuit and an additional circuit, wherein the amplification circuit may include a positive input port, a negative input port, a positive output port, a negative output port and a common mode input port. The photodiode bias voltage supply may be a floating voltage supply.
