Hello all,
I am trying to amplify low level signal by using Programmable Gain Amplifier (PGA)
but for Psoc 4 BLE there is no Such PGA component in psoc Creator.
but it is available for PSoc3 Devices.
does name of PGA name is changed for PSOc 4 ble or is there any alternative component for PGA..
Thanks in advance

There is no pga for PSoC4. You may use an OpAmp component and connect some resistors externally to adjust for the needed gain.

One way of making a PGA, SAR is set to use bypassed Vref in order
to get Vref for OpAmp. You can change the mux to switch the fdbk
loop. Might get a little less G error due to Mux Rdson. And better Zin
to the OpAmp. Also mux allows more than one switch on at a time so
possible to get 16 gains out of 4 R's.
Don't forget to bypass P1_7, the ref bypass option of SAR.
